i do have optifine installed . and this is the log

http://pastebin.com/1NFSLkSv

Looks like some block within salamander eye range (3 blocks) isn't registered properly. I am going to change the check in Salamander's eye anyway as it can be simplified and the registration name check omitted there, but the other mod definitely has a problem with registering their block properly.

I have released a version that doesn't use registry to check for fire so even if a block isnt registred properly this crash wont happen

it was either upgrade extractor from bauble stuff or the workbench from a mod called JACB .
