What the hell did EA do to TS2???

I’m a UC user so I’m only going based off of other people’s experiences, but it seems like LC introduced a lot of bugs that either weren’t happening before or weren’t happening as frequently. So what did they do to the code? It’s kind of baffling!! UC with all the fixes (4gb patch, graphic rules maker, RPC launcher) has never given me these issues that other players are describing, so they must’ve done something to the game beyond just these basic changes (god knows why). Has anyone in the community investigated yet?
