So hey, first of all I'd just like to say thanks to all those involved in taking up the torch and resuming development on IVAN! I first played IVAN 0.50 about a trillion years ago and always thought it had a ton of potential, so imagine my delight to discover that the latest version was just three months ago. But anyway.
I'm seeing a weird behavior and I'm unsure if it's me or if it's a bug. I haven't once successfully used a pickaxe in this build (0.50.8). Even if I'm trying to dig into a regular old crummy wall in the UT, all I do is spend one turn and get "You stop digging." Screenshot attached.
Even if this is an expected behavior, it seems like I should be getting some more specific reason about why I can't dig. It seems more like I'm just failing to perform the action for some reason.
I'm a regular old Windows 7 user. Let me know if there's more info I can provide.
Edit: Here's some more info: I found a meteoric steel wall and tried digging that, and got a normal message informing me that the wall was way too hard for my pickaxe.
You fail to free yourself from the bronze bear trap and your head is stuck in it in the attempt.
