As reported buff not working as description says, also I had 4 single loot scouts return just base, I own 4 experienced explorers so it was them, these are similar to savage scouts but different colour. The other effected were bewitched explorers, they return 2 x max loot, half of them only brought 1 extra loot instead of 2 & were not max. Its odd as all my bewitched skilled the same so only half bringing 1 extra loot is weird.
The cost of running this is not cheap so please fix asap.
