yeah, this happened to me too. What I did to finally open the game, is deleting some of the last vars in the variables section of Undertale Mod tool.

Yeah

yeah the only way to resolve this is changing the variable name to something like "_stringset", for example. That should solve it. Btw I think the problem is NOT undertale...

i think this got fixed long time ago. at least for deltarune. i remember modding deltarune was a pain in the ass by then
