[BUG] Error'd parts force a game restart!

[Gameslinx]

So, when installing a mod and accidentally miss something or don't install it correctly, say the plugin for example, and place the part on a vessel in the VAB or SPH, I came across this bug:

If it is an RCS thruster - the RCS ports will be on, firing out mono propellant.

If it is another part - see below:

If a part failed to install properly, this happens:

Select the part from the part list

Place is on the ship

The part sound will play, you will still hold the part but nothing will be placed on the ship

Clicking launch, save, exit or load will make all the buttons to remove the part or ship un-pressable

You cannot take parts off or move the ship around in construction

Menus don't work anymore

You are forced to Alt+f4, creating a crash log and losing the ship you just made

If this happens, perhaps display a message saying the error, the mod and the part, then exit to the space centre

This would help lose less data and time, plus annoyance!
