Did you increase the speed only the minimal amount to achieve full compression, or did you just double the speed and figure that people aren't likely to plug a yellow loader onto a red belt so it's okay if it's a little faster than it should be?
v0.0.1 only doubled speed for each loader, effectively turning them into the next tier version.
v0.1.0 has speeds tweaked down so loaders are slower than unpatched next tier.
