I'm experiencing an issue with the engine upgrade system when playing in Science or Career mode. When trying to open the RealFuels UI on most engines in the editor, the framerate tanks, and these errors get spammed in the console/log files:
[ERR 11:42:56.701] *RFUM: ERROR: upgrade SolidFuel does not exist!
[ERR 11:42:56.703] *RFUM: ERROR: upgrade Kerosene+LqdOxygen does not exist!
[ERR 11:42:56.705] *RFUM: ERROR: upgrade Aerozine50+NTO does not exist!
[ERR 11:42:56.708] *RFUM: ERROR: upgrade Ethanol75+LqdOxygen does not exist!
The same error also appears when purchasing an upgrade in the R&D building, but it doesn't get spammed.
Also should mention that the upgrade button shows some strange characters instead of the expected "+" or "X":
Not sure if this is an issue with RFStockalike or RealFuels itself, but thought I would try posting here first.
I'm running KSP 1.2.2, 64-bit. The only mods installed are RealFuels, RFStockalike and hard dependencies. CKAN was not used for installation.
RealFuels v0.12.0.38596 / v0.12.0.0
Steps to reproduce:
Start a new game in Science or Career mode.
Open the R&D building.
Open the debug console and give yourself some science.
Purchase Basic Rocketry.
Switch to the VAB.
Add the liquid fuel engine to your ship.
Open the RealFuels UI for the engine.
Here are my logs after performing the above steps and quitting the game:
