Woby Inventory inaccessable on Controller

Hey, just booted up a test server to check out Walter and noticed that Woby's inventory seems to be completely inaccessible while using Xbox gamepad controls (mouse + keyboard worked just fine).

using right stick up did nothing, even while using right trigger to toggle inventory mode. the selection box would get stuck on the ammo slot for the slingshot and would go no further up into other inventories.
