Billz, if you're in KM1 (can't remember the name of the mod outside if, if it exists outside KM), have you tried disabling that mutator "Nemesis Collisions"? I too didn't like the collision system, and a long time ago I tried to find a fix for it, and disabling that made me happy at least.
Sometimes on the early testings of GC, when I was trying out the engaging warp sequence I came across something funny, related to collisions and speed.
In the warping engage sequence, the ships boosts to a big speed to show her warping out right, so, in the "early" days of GC, it still didn't had a check to see if the path was clear. So on a few occasions, my ship boosted to that high speed in a straigth line, colliding with something (normally a asteroid or a ship that happened to be there). However she didn't stopped, she was destroyed but continued in a straigth line in high speed, even reached the point of the warp flash and all. Then she appeared in the "in warp" set ya know, with the starstreaks and all, spinning and exploding, ultimately being destroyed in bits, and leaving me stranded in that set :lol:
