So 1.33 turns out to be an interesting patch.
Red Raven is mostly unaffected, the only things that I've noticed are a quick menu sound (for example when you press "campaign" or "custom game") after 15-20 sec, so during the intro, and it also turns out that the Rot Dancer's hair has gone from greyish to pure white (default skin), which honestly looks better hehe. I've been working on the next patch for about three months (the changes and QoL-improvements are insane), but I think I'll wait a bit to see if I'm better off working on 1.32 or 1.33.
Ulven is really interesting. Whilst everything seems to work fine (i.e. no crashes), a lot of custom models, or rather ported models, have turned invisible. I haven't tried to import them again, but if I choose to stay on 1.33 that is the first thing I'll do.
I think my basic triggering skills (GUI-based) might have saved my maps from the crashes I've read so much about.
