Error using homotopic_steps

Hello everyone,
I run my codes by “stoch_simul” and everything works well, but when I run those by “extended_path(periods =constant)” there is an error that says:
Error using homotopic_steps (line 173)
extended_path::homotopy: Oups! I did my best, but I am not able to simulate this
there is no problem of the rank :The rank condition is verified.
How can I get ride of this error?

Have you tried the most recent unstable version? Note that the extended path is currently undergoing many changes and may not work. You might thus want to also try older stable versions. If that also does not work, provide the mod-file
