NullPointerException on startup caused by Twilight Forest

[Endoman123]

FML crashes when KK Re:Coded starts up in my modpack. I tested KK by itself and it starts up fine, so there must be a conflict somewhere. Unfortunately, the stacktrace/crash report gives no indication of where the conflict might be with my other mods.

[EthanGold60]

Have you tried the trial and error approach yet? Sometimes it takes a while depending on the number of mods are in your modpack, but sometimes it's the best solution when you can't find the error in the crash report.

[Endoman123]

@EthanGold60 I was hoping that there would be a smarter way than just "brute forcing" the issue; e.g.: are there any mods in the mod list that you recognize have conflicts with EnderIO?

[Endoman123]

Update: Apparently the conflict is with The Twilight Forest; should I create a new issue or is it something that isn't going to be looked at?

[Wehavecookies56]

Oh interesting, I'll look into why that's causing that then, don't worry about creating a new issue
