Its crashing concatenating the string on control.lua, line 6 with the CharcoalBurner mod_changes table...

Also, all the control code for resetting recipes/technologies could be moved inside a migration file, so it doesnt run every time another mod updates.

For last, force.reset_technology_effects() is a new command that does all the work of enabling/disabling recipes and effects for the current researched technologies, so you dont need to check if a research is done and force a recipe to be enabled

Can confirm, receiving same error.

Same error

same error - downgrade to past charcoalburner version and it works again.

@nagapito force.reset_technology_effects() does more than what you described, it also resets force values that were modified through console or control.lua. A good example would be game.forces["player"].character_build_distance_bonus and game.forces["player"].character_reach_distance_bonus which are both reset by that function. I would stay away from using this function for now.

That would explain why by distance bonus reset... thanks clampi!
