Placing/Removing redox cells causes massive, sustained lag

When placing or removing redox power cells of any voltage tier for the power sub-station, the server I am running locally experiences very long, sustained lag that lasts for 5-6 seconds per cell with the server spitting out "Possible lag source:" then some unrelated GT block.

Expected Behavior

Redox cells should be placeable/breakable without sustained lag.

Current Behavior

When breaking or placing a redox cell block, CPU usage of the server jumps to 100% and causes lag in the server as well on my computer.

Possible Solution

I don't recall if this was always an issue. It existed as far back as GTNH 2.0.7.5. It only seems to happen when I break/modify the cells inside the power sub-station.

Steps to Reproduce (for bugs)

1. Build a max size power sub-station except for the redox power cells (empty hull)
2. Open up the top 3x3 to start inserting new cells
3. Start placing redox cell
4. Experience lag

Context

Makes it extremely annoying for me and those on the server to upgrade the power sub-station.
