1. The custom battles in RS2 are fully functional for many factions, whether there are unit cards or not.
Custom Battles can eliminate problems with units before a player ever gets to the Campaign, so it is a Beta Testers job to
pound the crap out of Custom battles for every funtional faction!
2. Write down what units you recruit to play, and play against, an alternative to that is to save your army composition just
before starting the battle.
3. If you get a CTD in a Custom battle and there is no error, there is a specific procedure for finding the culprit:
a. Load the same faction you were playing, and the
exact same units you used before, and then load only one known
good unit from another faction. ALL of Carthage's units are perfect, so I always use one of theirs. This eliminates any
possibility of two units causing the trouble.
b. If it CTD's again, load one or two units at a time from the units you recruited, and test against the same Carthage or
known good unit. No CTD, cross them off, and keep doing this until you either find the one (by process of elimination) that is
causing the problem...or, you find nothing.
c. In that case, it was the units from the OTHER faction, which you wrote down.
d. Do the same thing with this faction, eliminating the good ones until you find the bad.
4. If you get an error message, report the error message exactly as displayed. I just write them down. Screen shots aren't
necessary but work as well.
5. If you got an in-battle CTD during a Campaign, load the same units in Custom Battle and test them as above.
