Crash On Save Fix for PC Head Tracking and Voice Type

For a few months I have been experiencing intermittent crashing on save which I recently was able to track down to the speaker detection in PC Head Tracking and Voice Type. On SKSE 2. 0. 20 the crash happens at skse64_1_5_97.dll+5CE66. Here are a few sample crash logs:

On other SKSE versions the dump and the address will undoubtedly be different, since the offsets and possibly function implementations have changed. Going through my older crash logs, I believe this could be an equivalent one for SKSE 2. 0. 19.

Here's the technical explanation for those interested: Through testing I was able to find out that the crash originates from the script _MAGSendModEvent.pex, and more specifically, calling utility.waitmenumode(0. 1) between creating and sending/releasing a custom mod event. I was not able to reproduce this crash with just the mod itself loaded, but removing this statement from the script completely eliminated the crashes on my full mod list without seeming to have any detrimental effect on the mod's functionality.

While I was testing the first fix I discovered a second type of crash which produced no crash log. This one I was able to locate originating from the Humanize feature of the mod, and this statement to be precise:

math. Abs(Subject. GetHeadingAngle(TargetRef)) > 90 as Float

I fixed it by adding a check to skip the statement if the 3D model of TargetRef is not loaded, so it seems that trying to get a heading angle to an ObjectReference that doesn't have its 3D loaded will produce a crash under some circumstances. I added a similar check to skip the statement if TargetRef is disabled, for safety.

TL;DR: There were some crashes, I did some testing and changed a few things in the scripts, the crashing should be gone now.
