Thank you for trying out the mod! I am sorry for your inconvenience. I will shortly look into this crash.

Here isthe trace from the link (for future me):

Error while running event tesla_legacy::on_entity_died (ID 4)
tesla_legacy/control.lua:413:attempt to compare nil with number
stack traceback:
tesla_legacy/control.lua:413: in function
'on_entity_died_handler_advanced_turret'
tesla_legacy/control.lua:434: in function
<tesla_legacy/control.lua428>

I had a look, and fortunately the issue was a simple typo. The problem should be solved in the new release I just created: 1.0.4.

new error, after overcharge technology

I cannot emphasize how happy I am that you are continuously supporting this mod by trying it out. The bug you have found was a bit tricky. I had to scratch my head to figure it out. Hopefully is is fixed in 1.0.5.
