I can't reproduce this issue.

Are you using mmap's from a repack or did you generate them yourself?

[Stoabrogga]

Extracted the data myself using the following steps:
(this already uses the new tool names introduced in commit 6017bf4)

• Go to the client directory:

cd ~/client

• Generate dbc, maps & vmaps:

~/vmangos-srv/bin/Extractors/MapExtractor -f 0
~/vmangos-srv/bin/Extractors/VMapExtractor -l
~/vmangos-srv/bin/Extractors/VMapAssembler

• Generate mmaps:

mkdir mmaps
cp ~/vmangos/core/contrib/mmap/config.json ~/vmangos/core/contrib/mmap/offmesh.txt .
for i in 0 1 13 29 30 33 34 35 36 37 42 43 44 47 48 70 90 109 129 169 189 209 229 230 249 269 289 309 329 349 369 389 409 429 449 450 451 469 489 509 529 531 533
do
  ~/vmangos-srv/bin/Extractors/MoveMapGenerator --silent $i 1>/dev/null 2>&1 &
done

• Wait until all MoveMapGenerator processes are finished:

while [ $(pgrep -f MoveMapGenerator | wc -l) -ne 0 ]; do sleep 1; done

• Move data:

mkdir -p ~/vmangos-srv/data/5875
mv dbc ~/vmangos-srv/data/5875
mv maps vmaps mmaps ~/vmangos-srv/data

Tested the maps from Brotalnia's repack (version 23) and the issue does not occur there. So there seems to be something wrong with the extractor tools. Will stick with the maps from the repack for now.
