Error 7 and Lava you Deeply
It was reported last week that players are having issues getting games on the new Lava you Deeply map. We monitored the servers over the weekend and looked into the reasons why that map was causing an issue. We discovered that players who had previously downloaded Lava you Deeply as a mod were seeing errors when trying to play with players who had not downloaded it as a mod. This is due to files which are shared across the mod version and the official version not being removed or replaced correctly. The game in these cases was exiting due to incorrect files.
There is a fix to correct this which is detailed below:
1). Right click and choose properties on Tower Wars in your Steam library list
2). Click on the 3rd tab named LOCAL FILES
3). Click on the button named "Verify Integrity of Game Cache..."
Once the game has run through and verified all of its files you might have several that will need to be re-downloaded. It should automatically download those files once the check is complete. Note: Once the process has been completed I would suggest restarting Steam.
Once Steam has been restarted you should be able to play the Lava Mines level without any crashes. There is a chance that you might get the Error 7 still if your opponent has not yet run the integrity check and fixed their files though.
If you have done all of the steps listed above and are still having issues when playing against players known to have the corrected files for Lava you Deeply, please post in the thread linked below to let us know.
