1. Issue with ThermalDynamics' CryoStabilized Fluxduct. Basic, Advanced and Elite cables work fine, but Ultimate...
   1a) Resonant Energy Cell, TE (it was full before I connected cryo-duct):
   
   
   1b) Vibrant Energy Cell, EIO:
   
   
   
   1c) Energy Cubes, Mekanism (I'll show 1 only, but its for all 4):
   
   
2. Issues with IC2:
   2a) U.Cables don't connect to wires:
   
   2b) Can't output energy (for example from MFSU):
   
   
   Mekanism 8.1.9 build 265.

to 1) :
#3077 (Mekanism-1.7.10-8.1.8.258)
It's same problem?

@laz2727 Nope, they dont store RF as they are cryostab. and transfer infinite.

@Adam4CZ yup but not for elite cables.

@Adam4CZ this means @aidancbrady has a bug in ultimate cable code, I'll look in commit that fixed #3077 and maybe will find something.
Upd. Didn't find that commit though...

@MineWitherMC At an earlier version I've tested all cables and this problem was only with elite/ultimate cables.

@laz2727 No, see in TheSprtCz's issue (#3077).
I've tested only cryo-stab. fluxdust and nothing happened. But when I connect Elite or Ultimate cable to cryo-stab. fluxdust, energy gets lost.

The issues you mentioned have been fixed.

Nope, they weren't. I tested them today (latest recommended build 265) and they happened. Then I looked into the commits that fix #3077 and didn't find any of them.

The fixes are in the development branch.

OK, will test and tell results. :)
