I haven't read every thread in this forum yet but I did get through the first two pages. Hopefully I'm not going back over the same things too much and hopefully this is the proper place to report bugs in the game. If not, please advise me where would be more appropriate (either here or on another website) and I'll put it there instead.

1. Companions lose weapons periodically when confiscated to go into a casino. Specifically, Cass lost several named weapons (Maria, That Gun, etc) and some "standard" weapons when we went into Gomorrah then came back out, she did not have any of them on her. This has happened three times now on three separate loads. Twice with Cass and once with Boone (Boone's was in the Ultra-Luxe). ED-E seems to not lose the things s/he is carrying, probably because s/he doesn't use the weapons (hypothesis only.)

2. NCR troopers seem to randomly be hostile to ED-E. I've had random troopers in McCarren AFB and Hoover Dam decide that, for some reason, ED-E is a hostile entity. This, of course, means I get to reload my save game soon after because ED-E dies. hardcoe + stupid bugs = reload.

3. Items/enemies falling through the "floor." On several occasions I've seen Rad-Scorpions pointing straight up in the air because they're falling through the floor. On one occasion, a Gecko disappeared into the rocks below me and my companions spent the better part of five minutes stalking the "hidden" gecko. This has happened near the road from Goodspring to Primm and in Scorpion Gully. Also, items dropped fall through the floor in various places. I lost three suits of Power Armor and one Gatling Laser through the floor in the Hidden Valley Bunker. The same sort of thing has happened in the Lucky 38 Presidential Suite.

Workround for issue #2: what I've found is that if you turn ED-E to melee attack before entering any neutral area (or you could leave him on melee all the time, like I do) he will not become hostile to other parties. ED-E has no melee attack and because this has worked for me, it would seem that it is actually ED-E that is going hostile and attacking other factions for whatever reason. (This may not be a bug depending on his programming, but as I've not fully played through his quest I wouldn't be able to tell you.)

i had the ede thing too in mccarren..it was that one dude that was leader of the rangers there kept goin nutts every time he saw him..
