I've managed, to an extent, make the Neural Parasite (With tentacle, mind you) be managed and make the Infestor able to move while mind controlling the unit. The biggest issue, now, is the glitch side-effect: When it expires or the mind controlled unit dies, the tentacle doesn't dissappear. It merely stays there, right at the spot where the former unit was.
Has anyone an idea of how to solve this? P.S: It's modified original, not duplicated or anything.
