When buying investments periodically the rounding errors on the account, where the investments are payed from, seem to accumulate. So it might appear, that the payment account suddenly has a saldo differing by +/- 0.01 after an investment booking.

When I edit the corresponding investment booking, the error shifts from this booking to the next one in the sequence. 

When I save, the consistency check reports a problem, that has been fixed. After that, the error is back at the previous booking.


Reproducible: Sometimes

Steps to Reproduce:
1. make multiple investment bookings in a sequence, all rounding in the same direction
2. Save, to get the consistency error
3. after a number of bookings you should see a saldo differing by +/- 0.01
