Isn't it also not just a floodplain but also a highly contested border area which their intrusion has made even more complex and annoying. They are lucky Serbia isn't also walking over the river to mess with their stuff. Wonder if that will happen to the Free Republic of Verdis. https://verdisgov.org/ (which isn't totally a scam to trick people into forking over 300 euros to try and apply for citizenship).

(And also yeah lol them building that on a floodplain. [laughs in dutch])
