Minecraft Version

1.21.1

Immersive Engineering Version

ImmersiveEngineering-1.21.1-12.0.0-182

Expected Behavior

Placing an accumulator on top of a thermal generator should charge the accumulator from below.

Actual Behavior

The accumulator does not receive power unless is connected to a machine.

Steps to reproduce

I have a working generator, I then placed the accumulator on top of it and placed the energy input at the bottom.

I also tried a connector on the accumulator and nothing happened.

Can you check whether you see the accumulators charging with a multimeter instead of the WAILA/etc overlay?

I checked with both.
The accumulator seems sporadic. It charges and stops charging at weird times. It's not reliable.
It might start charging when I have it connected on both ends, but if I break it and place it back, it will no longer change.
Then if I give it a block update it will start charging.
