more auction house gui problems

[UltraBlackLinux]

if one enters something invalid into the price selector the whole gui just closes but the auction house retains your item in the create auction slot. This item persists even after a relog, and even after it has been added to the auction house

Entering anything into the custom time inputs disconnects the player: net.minecraft.server.v1_8_R3.CancelledPacketHandleException

The buy gui shows two pages even if only one item is present:
