Explosions dealing up to x4 damage

[Fabrix199]

Describe the bug

Explosions in SA deal 82.5 damage, but in some places of the map it deals up to x4 (usually x2). There is no consistency in how the multiplier of damage is given, some parts of the map simply deal more damage specifically only to player and vehicles, occupational or not. In vanilla GTA peds remain unaffected.

The damage duplication it's entirely relative to player's XY position and not the explosion, so if you put player1 inside the affected area that multiplies damage, and place player2 a few meters away, and throw an explosive in between the two, player2 will receive normal damage and player1 will receive extra damage. This works with grenades, satchels, rockets and vehicle explosions.

A video showcasing the effect in vanilla GTA SA. The location covers the whole staircase. As the Z coordinate is irrelevant for this bug, you can replicate this on the roof of CJ's house.

There is many spots where this persuades so it would useless to list them, but a few examples are:

I figure I would report this either way, as the fire damage is also different (nerfed) in MTA compared to vanilla SA, for some reason, although I'm glad for it.

Steps to reproduce

1. Step into an affected area of the map (described above)
2. Throw an explosive

In case someone suffers from it - fortunately, there's a effective way to patch it (for time being) from Lua side, see: https://discord.com/channels/278474088903606273/278520948347502592/1327738005745831978
