[Harleyoc1]

It's some sort of problem with the code looking for Tech Reborn when harvesting from the IC2 rubber tree. It works when installing Tech Reborn if you still want to use the mod before this crash is fixed.

[Harleyoc1]

Having looked into the code, it looks to be a simple fix. Right now, the code is defining the resin ItemStack before checking which mods are installed. Therefore it's trying to drop the resin item from Tech Reborn, which causes the game to crash as the mod isn't installed.

Harleyoc1 is right, I just havent had the time to fix it. Will be fixed in the next update.

Fixed in DT-IC2 1.0
