[0.18.21] Startup crash due to malformed mod at Util.cpp 83

[Fenix]

What I did: Started the game with my broken mod in the mods folder. Mod accidentally calls data:extend(...) with a technology whose name is set to a table (invalid key type).

What happened: Factorio crashed at startup. Error message from log file:

Code: Select all

   2.693 Error Util.cpp:83: Values other than strings and numbers are not supported as keys

At ROOT.technology
stack traceback:
stack traceback:
	[C]: in ?

What I expected: The standard broken mod, in game dialog box that gives the disable/disable all/restart/exit options.

Thanks for the report. It's now fixed for the next release.
