I am getting a lot of errors. I am running the Fusion Trains Mod ( trains don't use fuel ) and I get errors in control.lua. The line numbers are 844, 444, 443. Also in Alerts.lua line 58. It said it cause a non-recoverable error for Custom event (ID 216).
Thankfully it did not crash the game. Hope this helps. Thank you.
Edit: I have to disable this mod, the errors are continuous.
