Hello, thank you for reporting this issue.

Unfortunately, your played version seems to be an older one. As of the moment, back-updates for older versions are not supported, mostly due to real-life constraints on this single-person passion project.

Please consider playing on the most recent versions, as each newer version aims to fix known/reported issues. I believe the newest version is stable in terms of cauldron behaviour. Of course, if there are any issues there, please feel free to report them in a new Issue thread.
