Hi there! Not sure I understand correctly. Normally when you place the first foundation on the water by deploying the item, you use a regular, Rust building planner to place floors (triangle/square) next to it. "Plugins chat to the players definitely is not working". You mean, the little red hit box on the bottom is not showing up when the foundation explodes when the players place them in the wrong way? Normally it should show a red box on the bottom, saying "That's not how you expand your foundations! You only need to deploy one blue doughnut as a starter. Then take out your building plan, select a square or triangle floor (NOT foundation!) and build just like in vanilla.". In your config, there's a setting called "PlayerMessagesAsToasts". Is it set to true, or false? I'm looking in the code right now and either I'm mistaken, OR recently the ability for plugin devs to send any arbitrary toast messages seems to be missing, only allowing for pre-approved, translated messages to be sent. Currently looking into it and wondering if it's something that popped up this September's wipe, or sooner, but nobody bothered reporting it?
In any case - I will be addressing the issue of the lack of hint boxes this forced wipe in less than 48 hours. I'd highly recommend hitting me up on Discord, as don't have Codefling push notifications enabled and have to check in manually.
