F1 - Infinite Money
F2 - Instant Recruiting
F3 - Infinite Resources
The Recruiting Units/ Instant construction cheat is a bit buggy when constructing a certain houses or upgrading something, So i suggest to only use the cheat only when want to build an army quick and keep it off otherwise
You need resources more than 1 to get resources cheat to work.
If you don't use a certain cheat or got the effect already then disable the cheat to avoid crashes.
