Im having an issue with the fluid transfer option on v1.0.20 for 1.16.5.
Fluids will just not transfer though the tesseracts. a channel (fluid tab) is created and selected on both tesseracts, the pipes get also conected and their direction is setted correctly, but the tesseracts won't transfer any liquid

I used 3 different mods thinking it was a problem with the pipes: Pretty pipes fluids, refined pipes and large fluid tank pipes. Y tryed placing the tesseract against a tank and it recieve the liquid without a problem, still, a pipe dumping the liquid into the tesseract is needed. I did some additional tests and sometimes the pipe recieve the liquid from the tesseract and others it doesn't. Don't know why though. Thanks for the help!

It might be the same issue as #15, but just with fluids. Placing a tank against the tesseract at one end should fix that.
What pipes are you using?
