Hello, I have some problems when using fastsimocal. Four populations (0, 1, 2, 3) are set up in the model: NHIN, NMIC, NNIG, NOTH represent the effective population sizes of groups 0, 1, 2, and 3, respectively. MIG01, MIG02, etc., represent gene flow. The model is set up as follows: Group 0 diverges to give rise to Group 3, Group 3 diverges to give rise to Group 2, and a hybridization between Group 2 and Group 0 produces Group 1. The specifics are as follows:

5 historical event

10000 1 1 0 1 0 1

714333 1 2 MIGNM RES4 0 1

714333 1 0 MIGHM RES3 0 1

896666 2 3 1 RES2 0 1

971000 3 0 1 RES1 0 1

The error message is: "Simulations did not converge. MRCA not found! (2 lineages remaining)".

The specific tpl and est files can be found in the attachment. Where might the setting be incorrect?
