Bugs discovered in Sims 2 Legacy

I had specifically the missing sim bug multiple times now. Both times they were children (one toddler w/ household of 4, and one child w/ household of 2). In my case, it seemed to trigger after the initial loading of the family. I would close the game to take a break; load the family back up and the children were just gone. However, the game did seem to get stuck on the loading screen for a while; long enough that I had to terminate the program as nothing was happening for over five minutes (has loaded every other time in under 2 minutes). This could have triggered the bug I suppose. Regardless, getting stuck like that in loading is certainly an issue that doesn't always happen.

I discovered a bug in CAS with custom skins where you can't click the tick or the X button if you go to choose a custom skin. I also keep crashing when I try to go into a beach lot I've placed (only tested in Belladonna Cove) I can go into already created beach lots in BV without issue, I just can't place and then go into lots/houses mode to change ones I've placed. Very little mods just hair, skin, eye default replacements (and custom skin) and flora default replacements, no big overhauls/fixes and no terrain/water replacements.

I see we have same problem then hah. Same happened to me, before kids disappeared they had wrong names (other Sims names) or names which looks like a names of files(?) in files game. I am so pissed off, I play ts2 for so long but unfortunately had to buy ts2 legacy. We spent so big money but still game is unplayable
