It's kinda obvious why the booster didn't work and it suddenly did when you played an official mod.
There are certain measurements takin' up to avoid farming. For instance, if you set a certain reaction time or certain MF/TF (not sure what this 'certain' is), you won't gain any TC via booster because that 'certain' is considered as farming.
Eg. 1 reaction time, 100 mf, 100 tf
Matches go by in a few seconds and if you set it to a mod where one player will always win, it'd then be farming.
