Hm.. this is weird. Try removing Index.bin file and RMGTemp folder from <game folder>/data and launch MMH55_Editor_64_NCF again.

@dreadknight

YES! it worked, now when i open MMH55_Editor_64_NCF.exe or MMH55_Editor_64.exe i see new creatures

Though i have generated a map through ARMG in MMH55_Editor_64.exe,
then opened it in mapmixer and only checked NCF and pressed OK,
then ihae started scenario with this map through mmh55_64_NCF.exe and there is one thing - i have cleared half of the map and i only spotted new creatures once (screenshot below), all other creatures camps were standart

Is this normal? What can i do to make this new creatures appear more oftenly? i have used 2p template map

By the way i have also noticed many creature camps were in stacks, serveral creatures types in camp not one
Also i didin't manage to use ARMG through MMH55_Editor_64_NCF.exe - it crashes while trying to generate map

Thank you!!
