Does this apply even when you are firing full auto like a mad man (which is pretty common practice in Doom)?Actually, speaking as someone who has fired real guns, a muzzle flash is nigh invisible in the daylight, and late at night, barely exists for long enough to see it clearly. If the muzzle flash exists for any longer than one tic in-game, then it needs to be shortened, as that might be the problem right there.
I will look at shortening it. But I like its current animation (it is really pretty how it dissipates)

I would say knife is overpowered in HTicJust tried this with Heretic, and I have to say it's even better there; you can get more use out of knife attacks, which is nigh on insane to try in most Doom levels.

But having no hitscanners to worry about is a nice change.
This is because the monsters are not yet RGH-enabled.-No exp gained from Heretic monsters.
I have no idea why this happens-The cursor for Heretic's item menu appears above the menu itself.

Also, IMPORTANT:
THERE IS NOW A BUG TRACKER
If you are reasonably sure you found a bug, feel free to post it into the tracker. The tracker has several advantages:
1) I won't miss (or forget) your bug report - it will get to my attention sooner or later.
2) You will know exact outcome of the report (either it was solved, or it was closed for a specific reason)
3) It will reduce clutter in the thread.
Please, look there and if there are any bugs you know of, that are not solved yet, feel free to add them. All you need is Google account (GMail, Google Docs, Google Reader...any of those will do).
Of course if you are not sure that your issue is actually a bug, you can always post it into the thread and I will try to provide you with feedback ASAP (of course there is risk of me missing your post).
For now, please keep feature suggestions out of the tracker (let's see if it works for bugs first).
