[Inf-IT DAVcl] The problem of the disappearing events

Hi, Suddenly I was missing some events. It took me some time to find out why. When InfCloud starts up, it loads events between 3 months in the past and 3 months in the future (configurable, in my case it is 12 months both ways). Now consider an event created April 1 2018 that repeats every 1st of the month. Every month I change it (add a 'check' when it is past) so the davical entry contains the actual VEVENT (with RRULE) and a huge list of VEVENTs with RECURRENCE-IDs. This event seems to be shown only if the starting date falls within the months that are initially loaded. When it is a simple repeating event (just an RRULE, no RECURRENCE-IDs) it is shown correctly. Any idea what is going on here? -- Johan
