My players and I have run into an issue with adding Drift Engines to ship frames. The issue appears to be with the maximum allowed Frame Size for each engine.
An example would be adding a Signal Booster drift engine to a Small Frame ship. FG won't allow you to do this and will throw up; WARNING: adding 'Signal Booster' to 'SHIP NAME' - starship size is not supported.
The Signal Booster engine should be allowed to be mounted on any frame size below Gargantuan (Tiny-Huge).
We tested further and found that you can mount a Signal Ultra drift engine to ship frames above Medium; which shouldn't work.
Ship Thrusters and Power Cores appear to be suffering from the same problem with frame sizes.
Thanks for everything you do Samarex.
