I'm using babylon 2.4 here.
I've providing position vectors to the Vector3.lerp function. The result seems to be a string concatenation instead of arithmetic addition.
Below I'm just showing x, z coordinates because y is always constant
from: 2.000, 0.000 to: 2.400, 0.000
lerp percentage: 0.33589999999996506
lerped position: 2.0000.134359999999986, 0.0000
lerp percentage: 0.9552999999999884
lerped position: 2.0000.38211999999999524, 0.0000
so this is going from (2.0, 0.0) to (2.4, 0.0)
The 1st resulting lerp should be 2.134359999999986 but instead its 2.0000.134359999999986
