Ok, now that I have some time, I can explain what I mentioned earlier in a bit more detail.
Important: The following is my opinion only and should be treated as such.
First of all - There is nothing wrong with this mod and there is no need to change a thing.
if the Player decided to use another mod in these missions, there is the potential to crash the game (under a specific set of conditions.) I realise that the “mines” you have placed in the player deployment area was intentional (and rather Evil).
How to crash the game:
The error occurs when the player deploys a ship to a location where it can unleash a high volume of weapons fire the moment it warps in.
If you want to try this for yourself: (Because it might only occur on slow PC’s)
Mission 8: Argena Second - The Right Way
Weapon Loadout: Any weapon that has a Fire Interval of Zero and is not bound by a small Salvo.
(if you wish to try it for yourself use the Destroyer Anti-Frigate Shotgun but remove the salvo code)
As it stands there is no weapon available in this mod that meets the above criteria. However if the player uses another mod which does meet the above criteria the game will crash in these situations.
This is the only reason why I made the comment to consider changing the deployment, that way the PI mod will be compatible with any other mod. Although on the other hand, if all modders avoid using a fire interval of zero for a weapon, this particular issue will not occur
