I have seen several problems with 2.50:
Fresh install with UV 2.30, then patched to 2.50.
All reports from playing Scenario 19
Often when two TF (one AP each) are loading the same land unit then one TF continues normal loading while the other stops mostly after their initial loading (without loading extra supply) and steams to the set target. I have seen this with two ships not having the capacity of loading all of the land unit (like two 1500 AP loading a 4100 land unit) as well as with a 3000+1500 combination.
Once in a while TF with CS orders move to their target but forgot to load their cargo (not yet seen in new campaign but in continued save game, was much worse in earlier patches).
TF just leaving Townsville somehow managed to detect enemy CV taskforces my search planes were not able to detect yet( just southwest of Rabaul). Thus they retreat but not to their homeport but to Brisbane (proably to Noumea on the eastern side of the map). This is really dumb especially if TF from PM start to move to Brisbane as they are coming even closer to those enemy TF.
Some DD in this scenario 19, one Porter and some Farragut, did not receive a radar installation regardless how often I send them back. Other ships of these classes received Radar on their first voyage back to PM.
Some carrier torpedo groups upgraded from TBD to TBF but TBD pool somehow exploded to 800 planes, in a continued savegame it reached 2200 planes after all upgrading finished.
-> The TBD production stopped in 1939, why does it have a production at all? It is reported that only about 100 of them were in service as the US entered WWII.
Ghost squadrons appearing. I sent Lex and Yorktown back to PH for AA refit but left their fighter groups at Noumea for CAP. Somewhere in the process, either at arriving at PH or during the move, a ghost squadron appeared on these carriers as a subordinate to the carrier's fighter squadron with the usual A-20 image and a max size of 24. No aircraft or pilots available for these units once the carriers were back in Noumea. It is possible to move them to other carriers but the next turn they'll be back on their carriers but without merging into their parent unit. Maybe it is related to an upgrade from F4F-3 to F4F-4 that seem to have happenend in the process?
F-5A replacements, three months into the game with two months listed as having a replacement rate of three each. I have only received three in total yet.
I really wish to have an option to have some air units out of the aircraft upgrade mechanism, especially early on you want to keep at least one F4F-3 squadron in service until replacements run out.
Land units and lost equipment, sometimes when equipment is lost on the way (transport aircraft crashed or ship damaged) this lost equipment is not listed in the units equipment stats (neither as active nor as inactive) and they do not appear back as subunits some days or weeks later in Brisbane or Noumea. I'm speaking of rather small numbers of soldiers or material like cannons or engineer vehicles but they are missing somehow, especially hurting if your badly needed AA unit is missing some of their heavy guns. Equipment lost with sunk ships is usually reappearing like they should do.
