Following on from yesterday's major update, I have released a hotfix (v1.5.1) which addresses the enemy loading bug which was mentioned in the previous announcement. This turned out to be a larger issue with the save system which should now be a bit more reliable.
Full release notes for v1.5.1:
[list]
[*] Fixed a bug where the enemies that spawn in when picking up the keys in Maps 3 and 4 would not load correctly after a save
[*] Fixed the Luger pickup not being consumed if the ammo cap for the Luger had been reached
[*] Fixed some minor enemy animation issues
