No worries, I've been busy/distracted this week so I haven't gotten around to designing anything myself yet. I really like the idea of the tanker board, though I worry pegs might make it a bit more fiddly than it needs to be. I'll have to print some and try them for myself.
Please do I'd be very interested in your feedback. Happy to supply the original files if that goes some way to alleviating the workload - it's all for the passion of the game in a spirit of collaboration - if you have ideas to improve please do so I'm very new at all this.
