Oh that’s you then? Can you post or upload the decklist, I’ll check the code of each card in it. Might be another player’s card that interacted badly there, but checking your deck is a start.

What’s gameInCheckPlayableState:

• xmage allows only one active user’s response in time per game (e.g. only one choose dialog):

prepareForResponse(game); // clear user's feedback data
waitForResponse(game); // start another thread and wait user's data
if (response.getBoolean() != null) {
    return response.getBoolean(); // processing result
}

• if you call second dialog then the first will lose user’s feedback and never get it from a player (it’s a popular bug – game freeze – you can see a battlefield, clicks on it, write chat but nothing happens like game waiting someone);
• some abilities and effects can use choose dialogs for calcs or other things (example: mana type choose for usage);
• if a bad ability calls a choose dialog in wrong place like continues effect’s apply, trigger’s applies, etc – then it will broke user’s feedback chain and freeze the game;
• but xmage needs some heavy calcs with possible user’s feedback. Example: searching for playable abilities and available mana;
• so it uses “check playable mode” – it’s looks like mode without a user’s feedback (all dialog calls will be ignored).
• there is a runtime check to find possible broken effect with wrong dialog call – that’s error from started issue: Player interaction in checkPlayableState
