I do not know if this is caused by Xaero, or not, but once I enabled Tetra-Pak, this keeps happening.

This seems to be an issue with the UtilBooster mixin I use to make the bubbler module work. Seems that it doesn't take kindly to Supplementaries not being installed. Will fix soon.

As far as I can tell, this is a bug with one of Tetra Pak's mixins. Will investigate soon.

Should be fixed in 2455a32. I'll leave this issue open until you get a chance to test with a new version on CF.

Problem has been fixed. Thank you.
