Slight issue with depot windows in 29px mode
TTDPatch Version: 2.6 r1618, 2.5 r1615
Patch Feature: Depot window, 29px mode
See the attached screenshot. The engines are all H8 'Allegheny's, from the US Set, and available starting around 1941. In both 29 px and 32 px mode, the depot window's size tooltip reports "12 (6)".
