most of the times RU tech tree tanks are the "best" overall, like object 277 line, but i would advice to stay at tier V for a while till you get the idea how the game works
never hesitate to ask any questions,
i would advice to join Aslain discord, you can get way more detailed info there and probably faster.
i could not recreate this myself
sort of thing is also happening in frontline but if i understand it correctly your issue is not the same.
if you have 1 crew for multiple tanks you can only select the tank the crew is in
example crew is inside the Progetto CC55 mod. 54 when i press start battle i could not get crew into the Bisonte C45
a few things you could try out, but expect it is pc related and not the game itsel
a quick google search showed it could be related to anti virus blocking WGCheck.exe, is post from wows could maybe help

if that us not helping try check and repair
you could delete the WorldOfTanks folder at
C:\Users\PC_NAME\AppData\Roaming\Wargaming.net\WorldOfTanks
that will clean out all cache/configs
try to re install the game
but you also have to check if other games are working fine, could be that some driver is outdated
so it is not really pinpoint advice, just a few regular checks you could do
hangman will not return, the maker is not doing updates or left code for others for a while now and the game has changed to much for quick fix.
same for custom hangars
yup, someone waited till they got a (automated) ticket back from WG and then wrote this.
i know the community often make jokes that WG is stupid and i must admit they made (huge) mistakes, if it would be true that WG will kick people randomly they can close down fast. not 1 ceo would allow that to happen ever and will make sure to take steps to avoid that at all cost.
if WG will say "purple arrows are not allowed" cheaters would make them square blue and it will turn into a giant rat race. that is the main reason they do not talk in detail about cheats/cheat detector or proof that they have.
i do not think it is mod related, but more that the game could not handle it well.
the bottom of the tank is displayed correctly while the top not, so would mean it breaks for half (would not make sense)
i did encountered this myself a couple of times and always thought i was wrong, nice to see proof it is not always working correctly
