Error while installing worlds

So if I'm getting this right I need a new clean folder and then try and install the worlds again. Is there an order I should try or do I just try them randomly? Though I don't know what the point is if they disappear again and I need to start from scratch anyway. I feel like something's broken here.

RexyStorms​  I understand this is frustrating, but I really do need to know the order here because if it's about the world size, that's an obvious problem and an easy fix.  If it's NOT about the world size, we can look at other angles, but those other angles won't help if this is simply a matter of size.

I'm sorry, but I don't know how to say this more emphatically.  There are two branches here in terms of finding the issue, and they are mutually exclusive, and I NEED the information I've been asking for in order to know which branch to take.  Otherwise I can't help.

Every time your content disappears, you need to use a clean folder.  You don't need to transfer everything over immediately, since this is just for testing; just trash the folder with the broken content and let the game create a new one.  This part is simple.

I tried to install them again though I forgot to write down the order I tried in. I'm quite frustrated because I had them all installed successfully but they uninstalled without me doing anything and now they all just fail every time. And trying to install them isn't something I really feel like doing if they'll delete themselves anyway. And I'm also frustrated because having a fresh folder didn't really fix the issues either. And it just shouldn't be this hard. I don't know if it's an issue with my laptop or some settings or something. I wouldn't know where to even start trying to figure it out. I guess I can make a new folder again but as I said it's not motivating when they'll be deleted on their own. 

RexyStorms​  Take your time.  But the reason I need to know the order of the worlds is they're different sizes, and the launcher bundles installed content together into files that can't be too large.  I don't know the exact sizes off the top of my head, but I own all of these and can try for myself.

Of course, the issue could be something else too, which is why I wanted you to test different install orders—you might find that one order doesn't work despite the world sizes seeming to mesh well, in which case we can look elsewhere.

I was pretty sure I had named the worlds at least once. My apologies I didn't mean to be so vague. Now since I've been into other things lately and it's been some time I'm not sure I can remember the installation order but I'll do my best and do more testing where needed. I'll post how it goes as soon as I get everything installed again. Some of the worlds had uninstalled themselves without me doing anything as far as I know. All the worlds I'm trying to install are Sunlit Tides, Barnacle Bay, Riverview and Monte Vista. This is taking a moment because I'm back to having the install errors. And I've found no clear fix. Because even when I've tried on a fresh folder I still seem to get the same error. 

RexyStorms​  Again, please let me know whether the order in which you install the Store worlds matters here.  As in, does only the first world you install show up?  Or does only, say, Barnacle Bay show up and the others do not, regardless of whether you install BB first or later.

Please test this in multiple separate clean user folders.  You don't need to move your other content to the new folders, and in fact it's best not to for now.

Please also name the Store worlds so it's easier for me to refer to them.

I installed all the worlds successfully as I mentioned but they don't show up in game as options when starting a new game. Well one of them did the last time I checked. But the other 3 didn't. 

RexyStorms​  At least the issue with the EPs is fixed.  What I meant by testing was that you could start a new save and see what content was present, for example it would be obvious whether Seasons was loading.

Regardless, I would like to know which Store worlds you're trying to install, and in what order, AND whether the problem is that in another clean folder, only the first one installs, or only a certain world installs.  For example, does Sunlit Tides install if it's first.  And again, please make sure the thumbnail has changed in the launcher's Downloads tab before you try to install it.

Okay now everything works except I can only see 1 out of 4 store worlds in the selection when starting a new game. And I'm not sure if I have all the other ones either because I don't remember them on the top of my head so I gotta double check later.

Oh never mind. They had unchecked without me touching them. I enabled them now.
