It looks like there are some bad images in the module?

riverwanderer commented 2 years ago

We are all using the same module ok fine in an 8 player online game. However, when this player reconnected at one point he started getting loads of bad data messages to do with missing image and sound files (for files that are definately in the module). He disconnected and re-connected again and has been ok since.

Is this particular incident a Vassal v3.6 variation of this issue that I have experienced under v3.5 and possibly earlier? The common theme being images that are in the module but the user session doesn't recognise/find.

BrentEaston commented 1 year ago

There is no actual VASSAL code in any of these errorlogs. Possible Java bug?

I would like to take up this issue.

Fantastic, it would be great if you could sort this out.
