Your mods already appear as updated, sorry for the trouble and thanks for keeping them updated.

SteahmChip, what do you say about an update?

Thanks for the advice

ANY will prevent spam, depends on how severe reduction you wish to go.
(activate only ONE of these mods at a time, though you can subscribe to all)

3x Kost Kill Spam Infantry NSB = changes stats of infantry, (because more 3xsoldiers involved compaired to other units, stat changes may be undesirable for some players).

THANOS POPgrowth limits manpower generation, (1/5th , 1/8th 1/15)

THANOS 1/5th probably most similar to 3x Kost, start with that.
if you want even LESS spam, use 1/8th or 1/15.

To test without a play commitment activate one of the mods, run AI vs AI overnight fast speed 4 or 5 (console~ type observe enter, ~ close console) using one of the mods and then in 1950s, go back into the game and see how it responds to you working the map, making selections etc.

If you want to jump in without testing, I suggest THANOS POPgrowth limits 1/5th.

What do you recommend to prevent division spam, using one of the three new mods or is just one enough?
