Title says it all.

hwell-0.2.1 We are playing The Galaxit Project mod pack, there is no reference to the power crystal in the well book. I checked out the wiki on the power crystals and we have tried all kinds of different combinations to craft it, we finally just grabbed one and it will not charge and will not place down, it just pops off right away.

No it doesnt actually. You should provide the hearth well version youre playing on, what modpack youre playing on, exactly the issue and if anyone else is having the same problem that you know of.

Not sure what is going on here, but that is a very old version of Hearth Well, and the mod still had bugs. Maybe try to update to a new version and see if the problem persists?
