It seems that the Luculla forest area gets corrupted after I fight the bandits that ambush you while escorting Alfie to Silverglen. If I go to another area and go back into Luculla forest, the game crashes. If I save the game after the bandit fight and load, the game crashes as well. If I ignore the Alfie quest, the game doesn't crash. I've tried coming back to it after finishing the Hiberheim section, and yet it still crashes after the bandit fight.

This bug seems to have been seen before: http://larian.com/forums/ubbthreads.php?ubb=showflat&Number=522963

Im having the same issue. I have several .dmp files available but i do not know where to send them.

Same problem here, crashes when trying to get back to Luculla Forest after that fight, on the PC version

Yup ^^, I have the same problem, except I was too stupid to create a safe before the mission so I'm scewed.

I did a couple of runs of that quest. It seems it doesn't crash (at the moment) if alfie dies , so the problem is probably something to do with him being in Silverglen

Got a similar issue on Ps4. Save files got corrupted and unusable in the Luculla area, Alfie's quest might be the culprit.

For PC, you can email supportdos@larian.com, with a description of the problem and the report.zip file generated by the D:OS EE Analysis Tool.
Extract the zip file somewhere and run the AnalysisTool.exe. When that loads, browse to the install folder (if it is not automatically detected), optionally run the tests first, and then generate a report (it will be saved in the same location as the Analysis Tool).

The report will contain system and game information, as well as your saved games. To reduce the file size, you can delete most of the saves from the zip; in this case you could just keep one before the escort quest, since this seems to be reproducible, or if you've done that already, your latest save and latest working save.

If the crash is reproducible, the CrashDump files wouldn't be necessary.

Console saves can be sent, as well, but they would need to be transferred to a USB flash drive first, then to a computer, and a third party tool is required for drives formatted for Xbox One (see here).
