Wallet stops creating and listening to new addresses

[9z25]

After about 50-55 addresses generated, the multiwallet will stop listening to transactions to the new addresses it generates. Also, addresses will start getting reused when the "wallet.NewAddress(wallet.External)" is run at this time.

Using a different mnemonic will fix the issue until that one generates enough addresses.

Is there a limit set on new addresses, how do I expand that limit to allow an unlimited amount of addresses being created?
