You know, I was just thinking of that yesterday. I should have put the map version number on the edmaps so that the player could see which version it is. In the latest version, I added an airfield in Thailand on the eastern edge of the map at Nakhon Sawan - an airfield used by Japanese bombers to strike Rangoon.
I don't have BAT so I don't know which version it has. I think, by now, BAT should be up to date. Even if it has an older version of cztx_BurmaLower_1942 and _1944 then my missions should be OK.
The much older cztx_BurmaLower (in vpModpack) is way out of date. There has been major changes for airfields, more added buildings, train stations, and much better textures, etc. which are in the _1942 and _1944 maps. I highly recommend installing the newer maps if anyone is using vpModpack or adds mods to their Modact or DBW.
A side note: I noticed that I was getting a drop in fps from the "tree0=" in the load.ini file (in the latest version). Anyone can easily change that "tree" by changing the line of text to any other tree from any map.
