1. What did I do?
I placed an EM plant on my space platform to make processing units (blue chips).
I connected the EM plant to my acid producing chem plant, and waited for the pipes and plant to fill with acid.
I rotated the plant to remove the acid pipe connection as my sulfur production wasn't keeping up.
2. What happened?
I made several maybe half a dozen blue chips before noticing that the acid in the plant was not going down.
I took a couple of screenshots between production to confirm I wasn't seeing things:
You can see that the amount of acid is full (400 units).
I made one more blue chip, and took a second screenshot:
Acid is still full.
3. What did you expect to happen?
I expected that the EM plant would consume acid to craft the processing units.
I double checked and my regular assemblers crafting blue chips are consuming acid as expected.
