The way I understand how the mod works (reading messages in the discord from its devs) is it borrows a lot of assets, scraps even more and replaces many systems
while yes a lot will work, even more wont
I'm sure the devs are just covering their bases, but they warn users that even texture mods *could* cause issues
and while I'm fine with testing my packs, a lot of users are far more casual and would like some level of certainty on whether a mod will work/won't f*#@ with the main game at large
