When issuing a venture on one platform (PS4) the issued venture complete or not will not appear when logging in on another platform (PC). The reverse is also true (i.e. PC to PS4). The retainer select menu will show a venture is underway/completed, but the retainer menu acts as though no venture has been issued, and there is no option to accept a completed venture.

I think this bug has existed for some time now, but isn't noticed because not many people switch platforms they play on. I only noticed because I switch to PC because either PSN is having maintenance or latency issues.
