Old Skool crashing on custom maps

[Old UT Veteran]

I recently downloaded a sp map and after clicking on the "Custom Maps" tab while using the OldSkool menu, I get this crash. I'm assuming it can't find or create a custom map list.
I've re-downloaded and re-installed the mods and its files, but same crash - maybe something wrong with my UT build? Any help would be appreciated. Thanks.

I'm using 469a and this is the first time I've run OldSkool in it. I just tried to replicate your error and I got a similar crash

From the log it looks like UT goes through all map folders trying to create the map list and it does this several times.

One thing to try - with OldSkool enabled, in the UT menu go to Options -> Configure OldSkool -> Options and make sure the Use Quickmap box is unchecked. This will stop it caching and it will load the list of custom maps from your folder (I think) - it stops it caching anyway and should prevent the crash.

Nice catch, I was about to edit my post. I noticed that in the configuration file but I never recalled modifying any settings anyways.
I might've had an older version installed previously, with that option disabled. Props.
