I figured if you were only playing SP it wouldn't matter, but you run an identical server - so this is very relevant.

DO NOT allow the blueprint station, it can BP cryopod dino's and recreate any number of them!!

There is a game.ini config to disable it.
OverrideNamedEngramEntries=(EngramClassName="EngramEntry_BlueprintStation_C",EngramHidden=True,EngramPointsCost=1,EngramLevelRequirement=1,RemoveEngramPreReq=False)
OverrideNamedEngramEntries=(EngramClassName="EngramEntry_BlueprintStation_Metal_C",EngramHidden=True,EngramPointsCost=1,EngramLevelRequirement=1,RemoveEngramPreReq=False)

Also, it's not necessary, but if possible disable cryopods, if there's anything else able to make blueprints, the exploit can still be done
