Build Limit Queue Bug

This bug is certainly a very odd one. It occurs whenever you give a BuildLimit greater than 1 to any queueable unit. The effect is that the limited unit can only be queued to one less than the stated build limit minus the number of that unit that have already been produced. For example, if I give BuildLimit=5 to the Mirage Tank, I will only be able to queue up to four when I have not produced any yet, and I will only be able to queue up to three of them when I have already produced one.

There are two exceptions:

1. When one less than the build limit have already been produced, a player can then queue the final limited unit.
2. If any other unit is queued before the limited unit, a player will be able to queue the limited unit up to its limit minus the number that have already been produced. It will work properly, in other words.
