[HL2DM] Explosion effects don't show up in new SDK

[Bitl]

When exploding a grenade/rocket, detonating a tripmine, or throwing explosive barrels, explosion effects don't show up after they explode.

This has been tested in both an unmodified SDK and my personal modified fork in multiple build configurations with the same results appearing.

EDIT: forgot to state that this isn't an issue in HL2MP

Seems like I needed to verify the files of the SDK, strange that I got this issue but its fixed on my end now.

I reopened it because I found the possible cause: for whatever reason if you launch the mod from Visual Studio, this issue occurs, but it DOESN'T occur if you launch the mod exe.

I can confirm this is partly true. The issue seems to happen just when debugging HL2MP mod from VS, but not when using "Start without debugging" nor running from mod_hl2mp_win64.exe (as OP already stated).

Also, in the offending case, the RPG smoke trail effect is missing as well.

I found out this was already discussed in #730. Also, a fix can be found here.
