I wasn't getting errors without if (gear_done) then {}; surrounding the
uiSleeps, so I don't quite trust the engine was executing them, I also
question the ability of uisleep to handle single frame precision (but I
haven't tested anything regarding this yet).
This is the code from 1.0.5.2 before it became 1.0.6, it contains the
fix for backpack wipes in 1.0.5.1. I lightly tested it with 1.0.6 but it
will need more testing before release.
