0.1.1b Strongbox not spawning all packs and getting stuck

Game version: 0.1.1b (as shown on log-in screen).

Found a strongbox in a Fallen Tower (Mesa) map, cleared full map (and activated tower) before coming back to the strongbox.

The strong box started spawning mobs normally, and it did cast lightning storm, as specified, but I did not get a rare pack, and the strongbox just stopped spawning and stayed locked:



I didn't actually count how many packs did spawn, but it didn't feel like 10 packs. More like 2-3 packs, then it just stopped spawning anything.

Also, the strongbox started as a magic rarity strongbox with an affix, I identified it, then used Orb of Augmentation and Regal Orb on it to bring it to this state.

Got this pb so many times since the last update ! strongbox stay close even all monsters are dead...
