Thanks a lot for the wonderful feedback! I will be fixing the doors soon and upload a new version. I found the knife pickup had some issues even in the test map for the IWALS plugin so I will see if I can fix that with better placement.
Regarding the build, I tried to use the shipping version but it was throwing a lot of warnings which were preventing it since shipping builds also fail on warnings. However, since I did not have much time, I chose to use the development build as a quick fix. I will put in some time to solve the warnings.
Thanks again for the feedback and hopefully, I can put up a new build with fixes and improvements soon.
