Using version 1.7.10-1.9.8. Getting this message repeatedly in the server console:

[elec332.core.multiblock.dynamic.AbstractDynamicMultiBlockWorldHolder:addTile:114]: ERROR!!! Tile at (-426,68,555) is trying to register whilst already being registered!

Also, each plug has a stable circuit in it, but the stability only shows up as 37%.

Also, coordinates are different each time, so they seem to be coming from different blocks.

This is not an issue with Calculator Locators. The issue is caused by mods which depend on Elec Core. So it'll be one of them instead. or at least coded by elec332

Oops, should have read that more closely. Thought this was the only multiblock in the world at that point - it is caused by Deep Resonance tank multiblocks btw.
