I've discovered a strange bug.
A certain image causes v3.14 windows to crash! I haven't verified it with the Mac and Linux clients.
WARNING TO OTHERS:
THESE STEPS WILL CAUSE YOUR CLIENT TO CRASH. FOLLOW THEM AT YOUR OWN RISK!
To recreate it:
1. Backup or delete the following file:
maps\parts\newmainmap\worlda-19.nw.png
(it is okay if you do not have it).
2. Put the following file in its place:
3. Run Graal v3.14 Windows
4. Log on to Graal2001 or Graal2001 Dev
5. (boom)
Renaming/deleting the file remedies the problem. Crashing does not occur on the latest v2 client.
Thanks to Tupper for verifying that it wasn't only me.
