TheBeast is correct in stating that Privateer's duplicated IDs finder cant track down GR2 IDs.
The chance of two randomly generated IDs being identical, is pretty low (there are are billions of possible IDs), but human errors can make this evenience more likely. Silent3ditor comes with an usufeful ID remapping feature, which makes the remapping of the IDs of a set of dat, sim etc. files possible in a few click. If you suspect that one of OHs buoys has some IDs vonflicting with silentmichaels mod, the said remapping tool might come in handy
