These seem to be the main problems with VCE:
Every time I used VCE and saved a build with it or something and it loaded as public, ALL the variable events broke and stopped working like how they are supposed to.
VCE REQUIRES the owner of the brick to be on at all times, and if there's no owner to speak of VCE just stuffs itself and dies.
The first issue can be avoided simply by not loading bricks as public.
The second issue is more of a problem. We would need someone to fix it if possible. Oh wait, you would need a scripter for that too - I guess we're stuck.
EDIT: If you need a VCE guy, Whirlwind is probably your best hope - or Big Brother, but idk if he's still active.
