Hello pluralmonad
I got an error when adding your mod.
Thank you.

Failed to load mod: Soviet-Tesla-Coils_V2/prototypes/entity/beams.lua:18: attempt to index local 'beam_table' (a string value)
Stack traceback:
Soviet-Tesla-Coils_V2/prototypes/entity/beams.lua:18: in function 'make_tesla_beam'
TeslaDestroyerRobot/prototypes/custom_beams.lua:50: in main chunk
[C]: in function 'require'
TeslaDestroyerRobot/data.lua:3: in main chunk

Thank you for the report. I've never used the Soviet Tesla Coils mod. Next time I load up my Factorio Dev environment I'll try to reproduce. Was it only those two mods you were loading at the time?
