Faulty -not enough data to comput flight curve

When computing the flight curve, in some case, rbms message that "You have not enough sites with observations for estimating the flight curve for species ...." when enough sites, visits or occurrence are present.

ts_flight_curve <- rbms::flight_curve(ts_season_count,
                                      NbrSample = 500,
                                      MinVisit = 5,
                                      MinOccur = 2,
                                      MinNbrSite = 1,
                                      MaxTrial = 4,
                                      GamFamily = "nb",
                                      SpeedGam = FALSE,
                                      CompltSeason = TRUE,
                                      SelectYear = NULL,
                                      TimeUnit = "w")

This was observed in some species from Catalonia BMS but is likely to have occurred elsewhere.
