if you play a level that lock player movement, boost or forced movement / 'gravity'(didnt confirm this one, happened once long ago, might be fixed) and the level either ends with this or you quit, you get permanently stuck with these effects unless a level overrides them
easy reproduction
- Open brohoof by misteriousShep, at the very start all movement is disabled
- immediately leave the level and play any other level that does not use movement lock triggers at the start
