What i've watched so far:
An RCE occures every time the value for a variable (byte, word, double-word) gets to big. Like setting "max number of systems" to 256 in settings.txt. This wouldn't be a problem if it is defined as word.
So my gues is:
Many Race-Styles and mods modify values and some programm calculations (like damage where random values are used) result in values not allowed by the variable definitions.
I don't think this are bugs in some of the mods or the game.
I simply think there are some combinations and results possible the developers haven't foreseen by allowing nearly everything to be modded (and that's realy understandable)
