Usage bits fix
|Reported by:||eriktorbjorn||Owned by:||fingolfin|
Sheesh, wasn't there any mistake I managed to avoid
when rewriting the usage bits handling? This patch
hopefully fixes the last of them.
See the following bug reports:
#670942 - ZAK256 crashes when turning on lighter in
#689095 - INDY3: usage_bits crash
#689157 - LOOM: usage_bits crash
#689210 - crash in catacombs
Of these, #689210 is the only one I've actually tested,
but I can't see any other possible reason for the bug.
(Famous last words.)
