Hostile unit glitch w/ missing hero & items

I reported this via bug report, but later thought I'd mention it here. I've experienced the hostile unit glitch two separate occasions, both happening after drafting a hero with a full bench and waiting until the following round began before selling anything.

In this last particular game, I had drafted an aurelion sol and wanted to wait until after my round began with 6/5 heroes before selling a benched hero to buy from my shop. The round started, I tried to sell one of my shyvana copies and it would not sell. I tried to sell a second hero (rank 1 vayne) to confirm I couldn't sell anyone, but to my surprise, she sold (the round was also ending at this point, could be related), then my shyvana sold next time I tried after that. At this point I'm noticing a hostile rank 1 vayne on my bench, then I notice the rank 2 vayne with guinsoo's rageblade is no longer on my board and is no where on my bench, and my rageblade does not exist on any hero of mine in the game, nor do the components.

I do not know why the game gave me difficulty selling my shyvana, but as for the rest, my guess is there was some faulty interaction between selling my benched rank 1 vayne and when the game booted out one of the 6/5 heroes in use, my rank 2 vayne with rageblade was picked and somehow my rank 2 vayne disappeared and the rank 1 vayne returned to the bench hostile and my item disappeared with my rank 2 vayne.

The only other time I've had the hostile unit glitch, it occurred on a unit I sold during a match with (x+1)/(x) heroes active in a game, but previously never had a copy of the sold unit in the round. Also, maybe it's RNG which unit is picked to be benched at the end of the round, and the game has to randomly roll a copy of the sold unit out of active units on the board in order for it to go missing (with any equipped items).
