World creation error: couldn't find unit description for unit type 'Levy Spearmen'. Help solving this problem please.

[FJMS1988]

Hello everybody, I have a little problem and I would be very happy if someone could help me. I have been deleting some units in the Stainless Steel 6.1 mod in order to replace them by other units I have created and I haven’t had any problem during my Early Era game. The problem is that I have tried to play the Late Era campaign and it appears an error during the AI turn that says:

World creation error: couldn't find unit description for unit type 'Levy Spearmen'.
Medieval 2: Total War encountered an unspecified error and will now exit.

I know the 'Levy Spearmen' is one the units I have deleted and I thought I had deleted all the entries where appears this unit in the game, but is seems that I am wrong and now I want to know how can I solve this problem. In which files can I found the references to the game units in order to delete the references to the 'Levy Spearmen'? I know the “export_descr_unit”, “descr_buildings” and “descr_strat” files, what else?

Descr_merc or rebels?

Ok, I have solved the problem, it was the "custom_script.txt" file.
