Bot rebalanced on a 100th+ coin by market cap

[Mothluin]

Hi
My bot is still configured to trade the top 10 coins by market cap, but 2 days ago it decided to rebalance on LUNA2:

Needless to say this was totally unexpected.
The day after, LUNA2 was obviously included in the coin list the bot invested in:

2023-04-29T00:05:02: [CHECK] Rebalance not necessary

Only to understand 5 hours later that LUNA2 should have not been included in the portfolio:

2023-04-29T05:40:02: [CHECK] Rebalance not necessary

Selling the coin created some rippling effect on the others, which climaxed into... a rebuy of LUNA2!!

Again, I find this behavior quite odd.
Happy to provide additional logs, if required.

Thanks
