Hello.
I believe I've stumbled upon a Experience bug with "Mahou Tsukai". (The bug happened once with the magic circles and didn't happen again idk why)
To recreate this
I made a 10x10 box where I had a Magma slime spawner in the middle (Maxed), placed 8 magic circles with the ritual "Boundary of drain life".
I was farming Mahou for a morgan, I needed to craft some powdered iron for the last circle and I left for like 30seconds, I came back and got +9k levels somehow.
Before the restart of 2:25Pm (GMT+2) as of writing this post I had 1.3k levels of experience, I somehow got ~1000 levels from a enderdragon kill when Cameronap asked me if I wanted a dragon egg and I teleported to him.
I was there when Cameronap discovered a bug which killed players in a claimed area with the mod. I didn't know which spells did that, so I didn't ask and wanted to do some Mahou crafting for a morgan, but didn't know there was another spell that possibly caused a bug.
I'll post a screenshot of this report in the #technical_support section for ATM6, because I can't attach a screenshot here.
I hope I don't get banned for this bug, but try to ban it.
