So I own a server and after working on a builder block I tried to open the manual which crashed my game, as well as the quarry shape card. The shape card crashes when you click on anything in its interface and give this message : https://pastebin.com/PnEFKyiT

I've tried getting a new version of rftools and getting rid of optifine. Any help would be greatly appreciated.

This is an ancient version of rftools that you're using. Updating to latest should fix it

Updating it gave this error while starting up

The game crashed whilst there was a severe problem during mod loading that has caused the game to fail
The game crashed whilst there was a severe problem during mod loading that has caused the game to fail
Error: net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from RFTools (rftools)

Updating to what exactly. More details please

Updating the RFtools to version 7.15

Ah you need to update Open Computers. @josephcsible can tell you where you can find that
Or else update to 7.14 which doesn't have that issue

Use the experimental build of OC that I linked in #1466.

EDIT: Now fixed in a new official release; see below.

To @josephcsible . How long before they release? If it takes too long we might need to rollback the changes to rftools because this is giving a lot of issues

I just asked them to do one. In the meantime, would it be worth putting a note about this on the mod's description page?

Okay, they just did a release (1.7.1.150).

Wow thanks you guys, that's insane I get to download a mod minutes after being updated (to me at least). I appreciate the work boyos. Keep em comin'
