Hi Mloren!
Huh, that double-food eating one I've never seen before. Tried looking briefly into it tonight, but nothing stood out to me yet. Will keep an eye out for it.
As for the slowdowns, I honestly haven't played a single session that long in recent memory. First thought is that it might be due to chunk-loading/unloading. But if it was coming and going frequently, might be something that just isn't optimized yet (or that I'm doing very inefficiently :P).
