RRRA's enemies shrink when spotted from behind

[Azatoth027]

When alerted with the player viewing their rear sprite, RRRA's enemies shrink, making it impossible to kill them with hitscan or projectiles. The only way is to use explosives, as if they were in the ground. So far I can only confirm this problem affects the bikers and cheerleaders.

You can see the tiny corpses of the bikers below the crosshair, slightly on the left.

I once saw a similar issue in the Alien Armageddon mod for EDuke32 where pigcops would triple in size when the player gets spotted in their back. According to DeeperThought, the problem is fixed in his mod so it might be a good idea to contact him. The report can be read here.
