Default TDC - Position Keeper Bug - FOUND

I found 2 bugs with manual targeting that may influence the 'aft' shot issues.

I put my sub parallel to a stationary target, so both fore and aft tube shots must turn to target about 100 degrees.

One issue is that the computed paths to target are not identical. If you switch from fore tube to aft tube, the 'X' target point changes in range. The 'X' target should compute the same from either tube.

Another issue is torp speed. On 'low' speed, either torp (bow or stern) exactly follows the green 'computed' path to the 'X' target spot. On 'high' speed, both torps make the turn with a smaller radius, so the actual paths are offset from the green 'computed' paths (but run parallel).

I hope this makes sense to someone ..... these symptoms should help locate the bug(s).
