You do have a non-zero range input, don't you? That would have been okay in the real TDC but our digital one has a cow.
The point is that the "POS" game works fine.
Apparently the word "tinnie" means beer in a small part of the British Isles. The word is predominately used in Australia to mean something that just doesn't make the joke funny at all, so that one isn't it. I encountered the term in a post on a radio control aircraft group where the poster gave a list of possible causes of a serious plane cratering and included "tinnies" in his list.
This Yank spent an hour chasing the term before figuring out what it meant. I'm getting some return on my investment!
By the way, sometimes the ingestion of tinnies is appropriate and sometimes it is not. As a service to the fine people over at RC Groups I made a flowchart so people can quickly determine whether a tinnie or three would be appropriate. Please substitute "Torpedoes Away!" for "Go fly" and "Target Sunk?" for "Plane in one piece" for use in manual targeting.
And please be careful to follow the chart as amended above exactly. Inappropriate consumption of tinnies can result in bizarre torpedo misses.
