There is one thing that used to work with Tweak Scale, and hasn't for a while. I use the Stage Recovery mod. When I scale up parachutes, they are not more effective for Stage Recovery. This worked at one time. It stopped working while I was taking a break from KSP, so I don't know when this changed. The work around is to attach lots of parachutes to large boosters. I don't mind, but the KSP editor is less responsive.

I think I remember having some tribulations with Stage Recovery while coding KSP-Recall - SR was working fine until Recall became needed due the crap KSP created recently about IPartCostModifier.

Check if this is something that needs to be tackled down on TweakScale or Recall, and move the solution to Recall if the later.
