 The Fat Cow release candidate: a CH-47 that lands in the field and becomes a forward refuel and rearm point for helicopters.
 DCS still has no native Fat Cow, so CTLD brings its own.
-Nothing breaks for an existing mission: the Fat Cow is a new F10 submenu, on by default, and `ctld-tools` adds its settings to an older configuration.

+## Fixed since rc14

+- **The Fat Cow works with a mission configuration written before it.**
+  In rc14, a configuration saved with an older CTLD had no Fat Cow aircraft, crates or loadouts: CTLD read the missing lists as removed on purpose.
+  A list CTLD added after your configuration's version now takes its default, and the startup message names it; opening the configuration in `ctld-tools` adds it for good.
+  A list you removed yourself stays removed.

 - **Mission makers** can place a late-activated CH-47 escorting a named flight (`fatCowAICows`, with the loadout to carry), and change the crates and loadouts (`fatCowCrates`, `fatCowLoadouts`, with a `menu` field for the Russian and Mixed submenus).
 - The stock is finite and guarded: if another script refills the FARPs (as the VEAF Mission Creation Tools did on every player join), CTLD puts the cow's own count back.

+  An older configuration gets their defaults, from CTLD at mission start and from `ctld-tools` when it opens it.
