ShulkerBullet NBT gets corrupted when (Owner,) Target and Pos position are equal

When two Shulkers are at the same spot (it seems like this can happen in normal Survival as well) and shoot, they hit each other. This causes the ShulkerBullets to have for Pos, Target and Owner the same coordinates which leads to NaN values for the Motion, TXD, TYD and TZD.

Possible reason

Probably because somewhere it divides the distance by the distance to the Owner maybe, because 0/0 = NaN
