Whenever anyone launches a spaceplane on my server, you lose reputation. This happens even when just launching a spaceplane and recovering immediately. Does anyone else have this issue, could DMP (the only mod that we have installed) cause this? EDIT: After testing some more I'm not sure it's related to spaceplanes after all. We just randomly lose reputation for no reason, for example I just went to the moon, did some science went back. Had about -250 science before and -500 after.
