Yeah, exactly what I though Below that part, at line 406 you have the passenger and cargo counts of accepted pireps, which uses laravel's whereIn() function and fails because your placeholders passing the maria/mysql 65k limit.
If you check the latest update/version of my Disposable Basic module, you will see that I limited it and now it should pass that line, do not cause an exception and work without pax and cgo counts.
BTW, my idea reversing the logic causes inaccurate results due to cancelled, deleted, rejected pireps.
Hope it helps. (at least until we find a better solution)
