I recently got version 1.6 and I'm experiencing 2 glitches (updated from 1.4).
1. The new part variants are not working. I select a desired variant but once I launch the vessel, it is reversed to the original 1.4 variant. This also occurs if I save the vessel and then reopen it. The issue is only with variants added in the two newest updates.
2. The deltaV is not accurately displaying. I have certain stages that have more than 0 deltaV but the readout still tells me that the burn time and deltaV is 0. Some stages (which include engines and should have deltaV) do not even have a deltaV amount displaying (i.e. they appear the same as in version 1.4) Once I stage the rocket to the stages that show no deltaV or 0, the deltaV pops up showing the correct value.
Any help is appreciated. Tell me if I should clarify anything.
