This is new, it didn't used to do this, however I also havn't updated the version of Botania.

I've already killed the second version of the guardian twice without an issue and died to her another few times besides that.

Something is messing with the datawatcher. This is not a botania bug, that mod shouldn't be doing that.

Nope, there's no way I know of to know just from the log, doing a removal test may well be the only way.

Alright, I'll take a look. Would you have any idea at what might be doing it, otherwise I'll start removing stuff till I can figure it out.
