is my NL acting up ?

lots and lots of exchange coasters are vallying

and lately my designs surprise me that they do not have the inertia they should in order to complete layouts,

as if somehow its settings or programming changed

i use v 1.55 and maybe tracks in later versions calculate differently ? i find it odd that 3-4 of these recent exchange tracks do not complete circuit.

Upgrade to 1.6. NL 1.5 does not have the 'improved friction' feature, which is why your coasters are valleying. 3-4 of the tracks you have ridden were made with improved friction on.

thank you! i look forward to upgrading it when able.
