The Hydrator from cyclic doubles any item you shift-click from your inventory into it. it doesn't work if you do it from your hot bar tho

This has been fixed as of v4.3

ah -.- thats why it didnt work for me when I tested if it was fixed...

This is a bug which existed in the previous patch which apparently is still a problem.

Can we get a follow-up on this in pack ver 4.0 if it's still a problem?

This is still a problem in v4.0
