When I assign an EU P2P tunnel about 30 seconds later it stops working and I have to reassign it with a memory card.

This was in FTB Beyond.

• Minecraft Version:
• AE2 Version: rv4-stable-1
• Forge Version: 12.18.3.2422

It seems to happen around about 15 seconds after setting it.

not sure if this is an EU thing there, do other p2p work normal if you set em up in the same location and binding?

did you double check there is enough power capacity in your system and subnetwork where the p2p tunnels are? (input is limited to capacity/tick having unlimited input means nothign then, or try with a creative energy cell for testing)

please provide a few screenshots including the p2p endpoints and the connection in between (if possible)

I posted a video of it here: https://youtu.be/efs4Fe2mX_g

Hmmm. that does look fine setup wise indeed.

1.10 Forge is somewhat unstable and can led to dataloss. Probably not in this case, but it's hard to ignore it.

Could also be a bug with the EU P2P in particular. I rewrote a good amount of them and the power system for 1.12, which fixed some edge cases. But this is simply too large to backport (as well as a breaking change). So it will most likely stay that way.

Some sort of periodic block update might also cause it to reset. No guarantees, but certainly worth trying.

I can confirm this issue is happening in the age of engineering modpack.
