When I enter my creative inventory and go to the next page with the IronMan mod and the latest version of the Regeneration mod, the game crashes. I am using the latest version of Forge at the time if that helps. Pastebin for the crash: https://pastebin.com/QTHkucWJ

Steps to reproduce:

1. Have the latest version of Regeneration and IronMan mod installed
2. Create or launch a world
3. try to go to the second creative tab
4. Game crashes

I expected as every time I use creative with mods, to be able to browse the creative tabs without crashing.

I'll have a fix for this out tonight, thanks for reporting!

Thanks for getting back to me so quickly
