This issue appears to be resolved - on my end, I can now load version 72 .p3ds, fixing not only Tanoa but a host of mod content as well. Thank you!

Note: If BI's fix for this will be to simply use the legacy Tanoa map files, please be aware most mods are now also binarized as version 72 and will also not be able to be opened by the Linux binary...as well as presumably the Jets DLC.

@Alwin, sorry for the delay with the reports. I had no idea where they were saved (as they cannot be generated from the launcher, as it is not available on Linux), until I saw @Jawsh's comment. FYI, @Jawsh, there were no mdmap files, not sure if that's a Windows only file...

Ah, I now see what you mean by troubleshooting report. As stated, I am on Linux. Unless I missed the rollout, the launcher is not available for Linux still. Thanks.

@Jawsh , I did verify the cache with no success. I will upload the report, but for posterity it is also now on my dropbox
