I have recently installed the latest 2.0.0-14.jar to test the functionality of the imperfect ritual. Every time I use the weak activation stone I loss 5000LP and my game crashes. I tried it on all 3 rituals with same result. Just for measure I installed the latest version of forge available. Same base problem I'm having, an interesting new symptom.

PS. Im gonna dumb my graphics as low as they will go maybe the special effects is overwhelming my graphics card....wishful thinking.

STOP MAKING NEW ISSUES.

To put my colleague's argument in a bit more civilized manner: if you have a crash, we need crash logs. Otherwise we can't do anything.

I will be sure to include a copy paste in the future. Until then I'll wait for the next blood magic update and hope the problem corrects itself.

@WayofTime This is a copy of my game crash when I try using any imperfect ritual.

It helps. (Remove extra spaces from the Tag)

Or, you know, don't post crashlogs as comments and instead link a pastebin. And as you have been told before, stop commenting on issues unless you actually have something to add to the immediate conversation.

It does add to it @TehNut , it allows them to properly format their post here, thus reducing dozens of lines of scrolling, especially if I'm in Mobile View where it forces me to scroll from the oldest post to the newest post, along with increasing readability of both this report and any future reports. (I've seen this happen countless times before, sorry if it spams you with emails to tell people how to properly format their Code Tags, but I'm looking forward to the long term benefits of the behavior)
