Error in Event log if try to deposit 100+ irons to bank

[Jaz 2,666]

Tried to deposit 222 iron coins into my bank at the token, which is naturally need 3 transactions as a single deposit cannot extend 100 items. The below lines are expected and correct:

[19:55:38] You may only move max 100 items at a time.
[19:55:38] Deposited 1 copper.

[19:55:38] You now have xx gold, xx silver, xx copper and xx iron in the bank.
[19:55:38] If this amount is incorrect, please wait a while since the information may not immediately be updated.

 

Then two lines which indicate an error despite everything went fine (I assume caused by the rest of coins above 100):
[19:55:38] Invalid amount; must be greater than zero
[19:55:38] Your bank is not available at the moment. Please try later.

 

Followed by repeating the amount in my bank.
[19:55:39] Your available money in the bank is now <same amount as a few lines above which is correct>.

 

It happened every time when I tried to move more than 100 coins, the last transaction which was only 22 irons worked fine without any erratic messages.
