[Bug]: path node binding doesn't work

[Alasdairbugs]

SuperTux Version

v0.6.3-1540-g9f4496832-win64

System Information

win 11 64 bit

Expected Behavior

using the bind feature to bind objects/coins to path nodes and path node arrays should work. it simply does not, instead, the origin path node doesnt recognise bound objects and any bound object recognises the origin, but not other bound objects

Actual Behavior

coin 1 says its bound to coin 2, like they have the same path ID
if i move around coin 1, coin 2 moves with it, fine
if i move around coin 2, nothing moves with it.

it looks like coin 1 is bound to coin 2 but not vice versa.

Steps To Reproduce Actual Behavior

i place coins in a pattern, give one coin "following path" and "circular".
make its path,
then assign the coins i placed in the pattern to a designated coin
