MMH5.5 - Heroes of Might and Magic 5.5

Hello everyone! Could someone please explain one thing to me?

My question is about the rewards for visiting various treasure vaults, towers, and other buildings on the map, where you can obtain artifacts, gold, resources, and spells (like the Ent's Sanctuary, Crypt, Mage Tower, etc.). When you defeat the guarding army in these locations, you only receive 100 gold as a reward. Is this normal?

The guarding army is quite strong, so it seems like the reward should be more substantial.

I generated the map using "MMH55-Utility.exe" and am playing through MMH55_64.exe, following the instructions. I'm using mod version RC18e, installed on a clean version of Heroes of Might and Magic V: Tales of the East 3.1.
