As the summary says, mithril medium armor should count as light for ranger abilities (yes, with proficiency for the armor), but it does not.

Pressing -> while viewing the Tactics and Combat Options page or <- while viewing the Character Generation Options page results in viewing the Macro Bindings page. However, the option description section at the bottom of the screen is not cleared, continuing to display the description of the last option selected on the previous page.

Occurs randomly; see attached picture.

Some vault doors are apparently intangible.

Autohide attempts to activate but fails when in "plain view" of a freshly-killed corpse.

My Dwarven Warrior-Rogue has a blessed circlet of blasting [5d8+2, 10d6+2, 5d6+2] (7 uses left). In the description for said circlet of blasting, it says that it has -450 of -450 hit points. This is probably not intentional and, although I haven't yet experimented with it, having just used a scroll of identify on it, probably also game-breaking.. Found in version 0.6.9I, which needs to be added to the version list.

When my level two orcish barbarian selects a target to throw his corrosive uncursed bolas of terror {good}, even if the target is not in a group, a window asking me what I want to examine comes up. After closing the window, the bolas are thrown as normal. This did not occur before becoming level two. Actually in version 0.6.9I, which needs to be added to the version list.

On multiple instances, I've come across a door at an intersection which leads to a room that can be entered by simply walking 20 feet in another direction. Not a serious bug, but somewhat stupid-looking.

The game should alert you when you attempt to do something impossible or enter something inescapable, such as attempting to disarm a trap with a DC 20 and a negative bonus or entering deep water when you have a total swim skill bonus of -11.

Title is self-explanatory.
