Issue from my daughters. Apparently if the redstone flip up or hang in the sky when you try to activate them? Known issue?
Yep, redstone isn't implemented yet. It's on the roadmap, no worries. The issue you're having with buttons and levers is because somebody (I blame @Intyre ) added a bunch of classes for new blocks back a few months ago but no actual code behind them. The issue with pressure plates causing suffocation is down to them extending Solid.
Do you not have something else they can extend like the one buttons use for now? It is only one or two lines for code to change isnt it?
