We lost power. If anyone spots it, please send it back. We need it. Desperately. Thank you to all the honest finders.
Spooky: reminding me of 1999 (except for no bombs falling)
Officials claimed that we have enough "electricity supplies" for the winter. Winter came very late (we had 15°C in mid-January!), but as soon as it dropped down to -10°C for around a week, power is off: this is most likely a problem with power lines or stations somewhere, but you still don't want that to happen at night with temperatures approaching -15°C, and only a minority of Belgrade population being connected to central heating system or gas network.
A bit less than an hour later, the power is back. Lets hope it will stay on for the rest of the year. :)
