Yes, unfortunately. I suspect it will get worse again in act 3 as the "stuff" in memory builds again.
And Yes Katarsi, the game keeps track of all the objects. Thats why when you leave an area and come back the stuff is still on the floor. The world is still burned/wet/acid/whatever.
I don't think the tracking of objects or memory usage itself is the issue because this works fine in single player. Theres a stark contrast between the switching in splitscreen. It's gotta be running a different segment of code somewhere.
I think the problem is that the game treats the split screen as two separate gameplays happening at the same time, so basically everything you do in single player is doubled in split screen - but the game attempts to stuff it in a single save. If this is the case, I can fully understand why it keeps choking. In DOS2 we were able to merge split screens into one, which means it was a single playthrough but with two players, and understandably everything was normal. BG3 on the other hand is literally splitting us in split screen instead of making us into a team. This is why dialogue options are repeated for every player, why we can't communicate with each other or to each other's followers and so on. The game is treating each player as the main player - and this is something that I think shouldn't be done in co-op. The main player (the account that had started the game) is the main protagonist, and the second player is basically their partner, support, and someone who should also have a say in major decisions (like in DOS 1 and 2). But we don't communicate at all. There's no merged split screen, there aren't things we truly do together. It's like one is completely unaware of the other's presence!
