FGU 5.1 Not working on mac

[rafaeladson]

Hi,

When opening a campaign on a M4 mac mini, the system just crashes.

This seems to happen for some campaigns, but not all of them.

We pushed a hot fix to address some of these issues about 4 hours ago. Please run a new Check for Updates, and see if you still have issue.
If so, please zip up your campaign folder, and provide a link to us; so we can make sure we address your issue.

Just pushed another hot fix that addresses an issue specifically with FX layers that could cause a memory leak.
Can you run a new Check for Updates; and let us know if you are still having issues?

Hi,

Still getting errors after updating.

I could not upload the whole campaign (too big, even when removing images/tokens), so I am adding the campaign files as attachments.

Please let me know if there are any others I should upload.

Hi,

Campaign available here: https://drive.proton.me/urls/5KCTDKM0NR#vFB0RfntGs1i

Hi,

I did some experimenting.

The problem seems to be with one of the loaded modules.

Not sure which one it is, but basically by removing all the <Loaded /> entries from the modulestate.xml file, the campaign opens again without crashing.

[rafaeladson]

Find out which one: Trying to load Battlezoo Bestiary causes the application to crash immediately.

[rafaeladson]

So far it seems to be the only one. Loaded a bunch of others and had no problems.

[Moon Wizard]

Thanks for the sleuthing; I'll try that book locally and pass along to Carl based on what I find.

[Moon Wizard]

Just pushed a new update that should allow your campaign and that book to load again. Please run a new Check for Updates, and let us know if still having issues.

Yes, it is working now!

Thanks!
