Well apparently if people claim that Vulkan is faster than any Linux rendering API (which clearly is) then I'll try switching to that. Also thanks a lot for the info
I'll try switching to Vulkan once I'll come back home. If it still doesn't work then it could be a bug in the engine itself and not the rendering stack.
You need more code to be able to gather multiple resources at once, and you need more code to make it drop a random resource. Your best bet would be to create three wolves templates with different resources OR to use loot as a way to have multiple resources (but then units won't carry the resources they'll be added directly to your resources)
Hey yeah this is a bug that will be fixed in the next patch release. Sorry for the inconvenience. In the meantime you should be able to switch to Vulkan in the game option
