Hate to say this, but the XCA wallet has become a joke.
You better not close it, and let it run 24/7, otherwise you are fked, restore, restore, restore....

If you need help with an error contact me on discord and I will help you.
really the only 3 errors I know are still out their are
TX not possible -> not the wallets fault, its the way the pools have been paying everyone in small amounts. if you use the CLI and type unspent_outputs it will show a lot like 200+
solution -> send smaller amounts back to back, or use the sweep_all function in the CLI to reduce your unspents. as time goes on and once the exchanges open the coin should be reduced from the unspents since transfers wont be only coming from mining pools.
Invalid seed or Invalid Password -> caused by using non latin characters in the wallet name. the password and wallet path are fixed but not the wallet name yet
0 balance when using a remote node -> this is because the wallet was going to the account summary page too soon before the cache was built
1.2.2 has this fix in it and will stay on the animated progress bar until it is done being built. the team tested it with one person today and it fixed it for them.
loading forever, this is because you need to run the wallet as admin. right click the exe and choose run as admin
hopefully this helps everyone
