Params in placeholders doesn't work

[nosooqua]

Hello again :)
I have issue with PlaceholderAPI. Params in placeholders doesn't work.

On screenshot: first value is value for %synapse_servers%, second value - value for placeholder that I send to chat.
(There can't be 0 players on the server, because at least I’m there :) )

I tried to use a 1.4 branch, but I haven't found where I can download MorePlaceholders 1.4, and I tried to compile MorePlaceholders from 1.4 branch too.
So, I can't compile that because some method doesn't exist...

I tried to understand the code, and fix the error in version 1.3, which I encountered. But if be honest I can't understand Kotlin 😄
From the code, I realized that params in PlaceholderAPI handled correctly, but methods like param.get(), param.single(), param["example"] is returning null...
Sorry, I tried to help, but I don't understand Kotlin...
