My friend reported this and I confirmed it myself that if an attackbox with DOT hits biker, OpenBoR will crash. I have tried disabling DOT and it doesn't crash so I'm sure it is caused by DOT.
You know, there's something we need to clarify about this DOT vs biker case. Biker is special enemy. If its HP is more than 1 or more than taken damage, the rest of its HP is given to dropped rider while the biker just leaves.
Now, in DOT case how should it be?
Carry DOT effect to dropped rider or just simply don't carry the effect?
I hope Damon Caskey would share some thoughts on this
Personally I don't want to give biker too many attentions unless bug fix.
You can always simulate the behavior with regular enemy+weapon, so dot can carry over.
