Note: If a problem is not listed as fixed above then it is probably not being addressed in this patch, but may be planned for a future one.

Note: When switching back from the Beta to the Release version, you may encounter problems with the controls. To resolve this, go to the in-game Start Menu and select Settings, Controls, Load Profile, then select the default profile from the list. Alternatively, if you make a copy of your inputmap.xml file before starting the Beta, you can simply copy this file back into your \Documents\Egosoft\X4 folder. Deleting the file will not solve the problem as it will be restored from the Steam Cloud.


Steam does not currently support automatic crashdump upload for 64-bit applications. We are therefore using a third party tool to provide this facility. If there is a crash then a standard crashdump will be created and uploaded to the third party site, from where we can perform analysis to determine the cause. As with Steam crashdumps no personal information is included in these crashdumps.
