All enemies now run a native init function to reduce script-induced problems.
this required adding a NOGRAVITY flag so that the recon can use the same code as well which was the only enemy relying on custom code.
As it turned out this is simply too dangerous - these should be left to be loaded from the map data or set manually.
All remaining setups using this feature have either been moved to Initialize or other meta properties that are not affected by map loading.
