The bogus point is close the place were Geo Awards Gala Event 2018 was held on february 2nd 2019.
At this point, about 60 m against west from Järviseututalo, you will find a sign. Look at this plate and figure out the coordinates to next stage by filling in:
a = E-P
b = 3*L
c = C-H
d = L+A+G+C
e = C+H
f = F+G+C
g = 2*L+3*V
h = (4*A)-(L+P)
i = 3*C+P
j = (H+V+F)*2+(A-C)

Continue stage by stage until you find a new place with some figures, let's call them ABCDEF.
Perform the calculation:
k = B
l = A*B+E
m = D-A+C
n = C+F
o = A+B
p = A+C+E
q = A*B-C
r = D-F
s = F-A*B-C-E
t = D-B
