Yeah not a huge issue but they might fix it eventually, idk, it's up to them whether or not this is an issue.
Removing dirt from the stockpile (or any resource) with an already growing tree on top of it doesn't remove the tree; so if one is growing it won't remove itself unless you remove it yourself. In my current stockpile the tree is placed on a rock tile. No new trees are growing on any of my stockpiles with various resources.
The wood stairs issue was usually resolved with putting walls on either side or the stairs to make them sit correctly. This always worked with the roof to do that while building and then it would stay correctly when the walls were removed. Thank may not be working this version
It maybe happened yesterday in a server whene i claim a zone of 100 block, the server was offline for about a minute and then the server restart without the structure of all player but i have the same inventory and skills
most important thing for you is the amount and that it works .. memory speed is not the most important thing for you to be honest ... why ? well having 2-3 ms or worst case even 1 second longer loading time means nothing really for you .. So ddr3 or ddr4 and the amount it can store is the most important thing =) .. and it working of cource
Tools shouldn't make an animation and sound effect if it has no effect on the area/thing your using it on. In that way it will be easier to learn where to use a tool.
This is pretty significant I think. The feedback is an important learning tool. Maybe a very audible 'wrong' sound if you use the wrong thing for the wrong task, like a heavy ugly thwang if you try to use an axe or a hammer on ore.
