Kerbal Space Program

i was playing sandbox and decided to take a crew report while i was transfer burning to dres because why not and when i hovered over the buttons on the science report and the length of the grey space after the delta v remaining after node extended, varyingly depending on what button i hovered over

i am running mods (alarm clock, an action group manager from before toolbar plugin (which amazingly still seems to work), TAC fuel balencer, module manager is in there,custom biomes, coherence contracts, fine print, trajectories, the ip transfer porkchop plotter thing, a modified folding wing from the remotetech 1 aeroprobe and a few custom flags.

i've also just unzipped and tested a stock install: the same thing happens.
and also in x64 and science sandbox (so also presumably career).

it may be in older versions but i don't have any at hand.

good luck with the bugbusting.
