Hi,

It’s hard to help without code but you might need to increase fusion too if you happen to have more than 10 states, as written by Krzysztof:

#define FUSION_MAX_VECTOR_SIZE 20

Can you provide a minimal code reproducing the problem? It is of course possible to have more than 20 transitions so you either have more than 10 states or your limit macro has been defined somewhere else.

HTH,
