In the penultimate trial, recover 4 missing vehicles , unable to interact with the watchtower

There has been an interactive area on the ground but it is still unable to interact. In addition, I don’t know how to switch vehicles after disabling the map in this trial.

@blackjack01 Hello.
Could you please send us a screenshot of the map with the location of this interactive area?

@Kir136 No way, maps are disabled in this trial

@blackjack01 Will the problem persist when restarting the trial?
If yes, please send us your save folder (C: \ Users \ * username * \ Documents \ My Games \ SnowRunnerBeta \ base \ storage), and also specify the trial name.
Also if possible, can you catch this problem on video?
