So, i got a variable inside a resource, below the code i’m using

extends Resource
class_name CustomResource
export (PoolVector2Array) var points

now, if i try to access the pool array, and just append points or set the size, it simply does not work.

var new_res=CustomResource.new()
new_res.points.append(Vector2(0,0))
new_res.points.resize(2)
new_res.points[1]=Vector2(1,1)
print(new_res.points.size())
print(new_res.points)

The above code prints 0 []

HOWEVER, if I declare points as an Array instead of pool vector2, it works as inteded and prints 2 [(0,0), (1,1)].
Is this a bug?
