**12/5**: In order to address the issues described below, we will be reverting the PBE to a previous build. [Check this update for more information.](http://community.pbe.leagueoflegends.com/c/bugs/4zEiHoBd-125-pbe-issues-update-feature-rollback)

As many of you have noticed, the latest update to the PBE introduced some serious issues into many game modes. Any map with inhibitors will always end in a crash, which makes game loop testing impossible. Our teams are working on a fix or reversion, but in the mean time, we will be shutting down queues for maps with inhibitors (Summoner’s Rift, Twisted Treeline, Howling Abyss including Showdown) until this issue is resolved. Our goal is to have this fixed within the next couple of hours.
Queues for Dominion will remain enabled, and all modes (excluding Showdown) will remain selectable in custom games. You'll still be able to test new skins, champion interactions, Yasuo, and other things even though most game modes aren’t functioning (again, you should expect that your game will crash if you launch a custom match on any of the affected maps). Though the majority of queues are down, we would love continued feedback on controls, tooltips, animations etc. Once we develop and deploy a fix, we'll re-enable the broken queues.
1. Summoner’s Rift, Twisted Treeline, Howling Abyss (including Showdown) queues disabled due to nearly 100% crash rate.
2. Dominion queues remain enabled.
3. All live modes are still available in custom games (but not Showdown).
4. After the fix is deployed, all queues, Showdown, and new player testing will resume.
