It keeps happening. Version 0.1.40 btw, on Factorio 1.0. I don't know what to do.

Hero turrets is now in 1.1 um if you drop this line in turrets.lua it should prevent it.
Add after Line 66 (im on my phone)
if new_entity == nil then return end ill see about adding a fix for 1.0 but just about to head of to work.

If your not experienced with lua its understandable jusy cant do anything right now

I will try that later. Thank you in advance. I'd play on 1.1, but for some reason it rejects all mods that are not tagged 1.1, even though in 1.0 I play with some mods that are still tagged 0.18 and one that is 0.16, all of which still work.

(Also, I am not experienced with Lua. Lua is scary. Hugs my precious Java)
