This is absolutely a problem, and the change occurred due to the May 18th update.
I have one particular bus stop with a backup of buses that I
never had before (the buses now, are in a queue of 8 to 10 busses long).
Before the update, when a bus would stop, it would take
almost exactly 4 seconds to debark and load customers, before leaving the bus stop (if there was traffic in the departure lane, it would wait for an opening, and only then would it take a little longer to depart, like an additional 1 or 2 seconds).
Now with the new update, I watched and timed the buses as they came and went for about 10 minutes, and I can tell you that some buses take the normal/standard 4 seconds, but many other times a bus will take about 8 seconds, and at other times a full 18 seconds ! There was zero traffic in the lane for the bus to depart, so this is not the cause for the departure delay.
This does not just happen at my "busy" bus stop, but I have observed it happening at any and all bus stops.
It's totally random when it happens, and I was wondering myself (as someone mentioned above in a prior post), if the programmers added some kind of timing to the departure, in order to "separate" the buses and keep them from "bunching."
Can we get some kind of confirmation from the developers on this problem/issue, please.
PS: I have
never had, nor do I currently have,
any mods when playing. I have the base game only (not even any DLC's). So if you want to blame and excuse this issue on a "mod," forget it .... it's not happening.
