Hi there

Here's the crash :

The mod Ammo Alerts (2.0.8) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event Gun_Turret_Alerts::on_surface_renamed (ID 143)
Gun_Turret_Alerts/control.lua:149: attempt to call field 'deepcopy' (a nil value)

From what i understand, it looks like your code here https://github.com/Wyrrrd/Gun_Turret_Alerts/blob/c08b964a8d013ff79ef2624371ade05db77b80cb/control.lua#L149C1-L149C131 is using deepcopy while you never have 'require("util")' in your code (so table.deepcopy doesn't exist)

(i didn't know if you prefer a message here or in your github)

As I depend on "base" which in turn should load util in, you might have a mod loaded that deliberately wipes util. Could you try to find it for me?

No it doesn't.
You have to explicitly load util to have deepcopy, otherwise it's not there.

Also my mod (dimension-warp) explicitly load util and use it, so clearly I don't wipe it...

If you want to test it by yourself, just create a vanilla game with your mod only and type:

/c local surface = game.create_surface('test_surface')
surface.name = "new_name"

and you'll have the same exact error (minus the stack from dimension-warp)

Nevermind, fixed it in 2.0.10.
