Mod issues with The Twilight Forest

[MayDay42]

Hi all, I've been playing a mod pack the includes the twilight forest. I never noticed this until last night when I went to actually use the mod. For some reason when I go to create the portal for it, the portal does not work. I am playing in 1.18.2, forge 40.2.15. I think I have narrowed it down to being an issue with conflict between mods but I am not 100% sure. I've never had this issue before, and even tried it with a mod pack extremely similar. The mod pack has the same mods just a few less and it works on that version. Any ideas? Thanks. (Not sure if I'm posting in the right spot)

make a new world for testing.

do binary search until portal works.

How do I do a binary search?

[TileEntity]

Remove the mods that differ from the working modpack one by one

[MFMods]

remove half the mods you have.

if that did not solved the problem, repeat (remove half of the remaining  half).
if it did, culprit is in the removed half. switch groups. remove half. repeat.

repeat until you find the culprit. then tell mod authors.

I found the issue. It was a conflict with Twilight and Gothic RPG. Thanks
