Crash Report: http://pastebin.com/xpyK4HBH

Forge v1558
Tropicraft v6.0.4

Please try v6.0.5 here: http://tropicraft.net/downloads/

v6.0.4 has a bug with NEI that caused this crash sometimes.

Cheers!

I saw there was an update and I'm trying that now; will let you know what I find.

Edit: Just tried 6.0.5, that seems to have fixed it, I can view the recipes of the different dyes and they show your flowers now.
