           Summary: Morrowind Mudcrab crash: creatures near water hit
                    animation/location errors
           Product: Wine
           Version: 1.1.12
          Platform: PC-x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: boyd.mon at gmail.com


After 100+ hours of playing Morrowind 1.2.0477, I've seen at least a dozen
crashes involving either Mudcrabs or Slaughterfish near a coastline.  When
approaching Vivec from the North I've hit it 2-3 times, 2-3 more times crossing
from Sadrith Mora to the coastline, and others in random places on the map. 
I'm reporting it since I annoyingly just hit this bug twice in a row - within a
couple minutes of each other.

The typical sequence of events is three pop-up boxes asking "Continue running
executable?  [yes] [no]" after presenting these error messages:

"SetFootPoint finite mudcrab0000011C"
(twice)
"footpoint qnan mudcrab0000011C"

After this third pop-up, the game reports that its "Saving", and once the
progress bar is complete, the final message ends the game when [okay] is
clicked:
"Actor Animation Problem with mudcrab0000011C
This actor has no animation class!"

Fortunately, I can then reload the game save named "Restore", which runs fine
after one message hints that the problem has been cleaned up:
"Invalid Location on REFR 'mudcrab0000011C
 Setting to position (4096, 4096, 0)
 Continue running executable?"

-----
It might be argued this is a Morrowind bug, but when I played Morrowind on
Windows I can't recall hitting this bug.  So at the very least, Wine &
Morrowind interact to make this bug fairly frequent.  Since this problem occurs
with Slaughterfish as well - which are only found in the water - I assume the
problem is with creatures near a beach.

The workaround is to keep running the executable until "Saving" appears, then
load the "Restore" save game.  I haven't collected debug output, and figure the
lack of this bug being reported means I'm probably playing Morrowind on Wine
more than most users.  So I haven't bothered with debug output, since I haven't
seen anyone else hit it.
