So I am using the SamVanheer Half-Life Updated Master (https://github.com/SamVanheer/halflife-updated) and I have a bizarre issue with sparks appearing above NPCs heads.
Here is a video to prove that I am not insane:

This issue is completely random, you can use an NPC 10+ times without it happening, it also happens at complete random whenever an NPC is moving. It is extremely distracting during scripted sequences and I am at a point where I'm just going to dump the Updated Master all together.
This issue appears in all my maps and all my test environments, I have absolutely no idea what causes this. If anybody knows how to fix this I would appreciate it or maybe there is a better master file for creating mods, I dunno.
