Directly after the Irrigation Trial tutorial I thought I would give it a try, but hitting R 3 times doesn't do anything at all, while hitting R 1 time brings up the irrigation UI in the top left, changes the cursor, changes my tool head and tells me I have 100% pressure... for maybe half a second, then it changes the cursor back to normal, though it keeps the irrigation UI sometimes _and_ keeps the tool head change all the time, but the pressure indicator disappears. Left-clicking during the flash of correct cursor does nothing, neither does left-clicking, and pressing R again just does it all over again. Is this not implemented yet?
