Multi-Nav: groups become stuck in a group

[rayanth]

Summary

If you have a group of trucks selected, with at least one having Multi-nav turned on, and cancel out of setting up multi-nav points, then the group will become 'stuck together' and continue to operate as a group even if only one is selected.

Game Version

Version: LOGistICAL Earth, 853u & 853w

Reproduction Steps

• Multi-select at least two vehicles. Ensure one has multi-nav gizmo, turned on.
• from the truck with multi-nav, start dragging a resource to go into multi-nav's selection mode.
• without selecting any destinations, hit 'done' (to 'cancel out' of multi-nav)
• turn off the multi-nav, and deselect the group.
• send one truck from the prior group to any destination, with or without cargo.
• observe that all trucks that were in the group follow. (if a resource was selected, they all will pick it up and deliver, etc)

Expected Behaviour (optional)

Trucks that were previously in group should not continue functioning as a group when the group is no longer selected, and the trucks don't have multi-nav routes in memory.

WORKAROUND:

To 'break up' the group again:

• Multi-select the group
• turn on multi-nav
• Plot a multi-nav route of at least two destinations (just one might be sufficient)
• Click Done
• allow the trucks to finish the route
• send the trucks to some location to 'dump' any remaining cargo
• deselect the group
• they are now 'broken up' properly.

Fixed in build #854

[valerius31]

On build #854(openbeta) the bug still appears. It can also be induced by the following steps.

• Multi-select at least two vehicles with multi-nav turned on
• Start dragging a resource to go into multi-nav's selection mode.
• Plot a long course that will not be completed
• When the vehicles stop, turn off multi-nav and move one of the vehicles

Reportedly fixed in 854d, not yet verified.

as of 855k, I haven't tried to reproduce this again, but there have been no new reports of it happening, so closing.
