TFS 1.X+ TFS 1.5 Nekiro 772 StorageValue change during travel

[Gover]

Hello,
I'm trying to make the postman quest working on nekiro 1.5 772 downgrade.
I'm struggling with the npc script which should update the player storage value, but it don't.

Here is an "action" function from addTraveKeyword:
addTravelKeyword('carlin', 110, Position(32387, 31820, 6), function(player) if player:getStorageValue(PlayerStorageKeys.postman.Mission01) == 1 then player:setStorageValue(PlayerStorageKeys.postman.Mission01, 2) end end)

I'm 100% sure, that player have player:getStorageValue(PlayerStorageKeys.postman.Mission01) == 1.
Maybe someone have an idea, why this function "addTravelKeyword(keyword, cost, destination, action)" ignores the "action" parameter in Carlin Travel?

Thanks in advance for help.

function onCreatureDisappear(cid)        npcHandler:onCreatureDisappear(cid)            end

Found a solution.
keywordhandler.lua had to be edited
