c7m1 tank punches are delayed

[Derpduck]

Reports that since TLS update the train car tank on c7m1 has "delayed" punches, particularly on high ping. Still not verified if this is actually the case, but it is likely to be a server/config issue but is potentially related to the map and worth looking into. It's also reported that holding +attack instead of just clicking does not have a delay, this needs to be verified also as this could be a ping issue with how commands are sent to the server.

There is no obvious cause I can find in the logic of the map that would change tank punching.

Here is a video showing the reported delay, but there is no point of comparison on other maps on the same server or any kind of normalized testing method to measure the delay: https://www.youtube.com/watch?v=l7kgp_ydWYA

I did a comparison on a local server, the bottom 2 videos are using net_fakelag 60: https://www.youtube.com/watch?v=cBRGKnxR-6s

3 potential causes I can see for this so far:

• The train car tank model behaves differently to the regular tank
• Tank is spawned using info_zombie_spawn
  • We use this method to spawn additional tanks on c1m4 and c5m5, so they will serve as good testing points.
• thesaccing.vpk is used by competitive servers to combine The Passing and The Sacrifice campaigns, while this is a very simple addon that simply overrides the campaign6 mission file, it has the potential to create issues.
  • The section for c7m1 is actually missing this line: "TankArmsVariant" "models\v_models\weapons\v_claw_hulk_dlc3.mdl" which sets the viewmodel for the tank's arms, this should only be visual but it's worth looking into.

It could also just be some config/server related jank, but I don't see how that would affect only this tank. The current Stripper file for the map in Zonemod does have something to fix an exploit related to the tank, but it's unclear to me what this actually does.

Have not had any more reports of this since implementation of thesaccing_v2.
