Can't open the milestones panel

I do have mods and CC, I took them out of my mods folder and it worked, so I'll try to see which one is causing this, thx

Hi! I have the same problem, but removing all mods from the mod folder does not solve the problem. The milestone tab continues to not open, when i click on it. The game otherwise runs as normal and i can see all the milestones my sims have, but when i try to click to open the tab nothing is happening, even with all mods removed.

@aNEKOni Did you remove the whole Mods folder or just non-CC? Did you also delete the file called localthumbcache?

I just started having this issue, but only with one particular save, which I downloaded from another summer. When I try to open it in a different save, everything works fine, even with mods enabled. When I try to open the milestones tab with mods enabled or disabled in the one particular save, it won't open. I don't understand why only this save has this issue.

@Jojoa777 Could you try this test on that save?

1. Do a "Save As" to make a test version of it, then exit
2. Rename the Mods folder or move (not copy) it to the desktop
3. Start the game, load the new version of the save, and try again

Let me know if that works

Thank you so so so much for your help!!

I just tried all of these steps, and the milestones tab still doesn't open in that particular save. 

I also tested saving a household from that save to my library and then putting it in another save. In that other save it worked just fine.

I realized I had a typo in my original message, it was a save from another simmer, not summer.

@Jojoa777 Ah -- so, there are definitely custom save files out there that are bugged, though I haven't heard of this particular bugginess. Which save file is it?

It's Fleuralia's Version 7 Save File. The weird thing is, I was previously playing with the same creator's Version 6 Save File and everything with that one works fine (I even tested it today). I have also messaged the creator to find out if this is a known issue.
