Well, my best guess is FA ... when limpet is dropped in inherits everything from ship in code, including FA. FA itself could look like broken phys. as it starts to brake. Then inheritance explains difference, T-10 has bigger difference with limpet then ASP with limpet. So fake-limpet-FA does less mistake on aspx.Perhaps a quick-fix might be to make prospectors intangible for, say, 3 seconds after they launch so they can get clear of a ship?
Any way, it's just code bug either FA or phys, should be fixed.
