[SMBX2 Beta 4] Debug Error that appear when loading my episode

[ArchCaff_Gamer]

Essentially what's happening is my levels, which have custom NPCs and the like, work fine when testing them through the editor, but break completely when playing the levels as an episode. The worst part is that it seems the error also results in every other NPC (including non-custom ones and even BGOs) to completely stop working or render properly. I'm not sure how to fix it because I've done research and no posts I've seen have covered this issue. I should mention that I suck at coding. Here's an image that may help:
