Using this on 1.16.5, when I right-click the evaporator without any liquid, everything works fine, but if I put lava in, then right-click, the game crashes. I'd include the log, but it ends without mentioning anything but the last command I typed (/give @p lava_bucket). No crash logs were generated either. As long as I make sure to not touch it while there's liquid/items in it, I can just extract with hoppers, though.

Thank you for opening an issue on the Alchemistry Repository!

A few months ago Alchemistry has changed ownership. The new team has rewritten the mod from the ground up for Minecraft 1.18.2. Support for all older versions is being permanently dropped so the team can focus on newer versions.

Your issue as reported might not be present in the newer versions. If you encounter this issue again in a newer version, post-rewrite, please open a new issue.
