it makes perfect sense that this wasn't a huge update, honestly. you have to realize that most of these devs are likely not the original ones, and they're almost definitely trying to work against really bad code from other people
if you know anything abt programming, you know that it sucks really hard to try and even read old, badly-commented code you made from years ago, much less old code from others. imagine that, but with 10 years' worth of other people constantly adding code without ever improving it. imagine being the person who chose, willingly, in this dumb-ass video game company where nobody takes responsibility for their own bugs, to try and fix it. the fact that the few people involved managed to actually fix a few really important things at all is a fuckin miracle
