Hey,
I was trying to change the message that comes if you try to place a twig foundation or a ladder - but it's not changing. I changed the json in lang and even the message in the plugin file itself - but it still just says the default message. What am I missing here?

Hello,
if you modify it in the source file, then it need to change for sure. In an ideal case, not even a plugin restart neccesseary, but recommended. Are you modify the correct language file in the given national folder? Like ru/eng/fr etc? And your rust language set to the same where you dothe edit?

I put the same file in every language folder, yes. And reloaded the plugin several times, but even after a server restart - no changes.
