Yes, it is true that I spawned at an altitude of 23000 feet and I immediately pressed the menu that lifts the aircraft altitude 2 times from 23000 - 25000 feet and I saw engines 1 - 4 rise dramatically until they passed the safety limit.
When did this happen? Did you use time skip or did you use the quick lift up function or did you spawn in the air at high altitude?
I've been there before too. I was flying from Narita to Honolulu on an A380-800. After taking off under my control, climbing on the autopilot, and reaching cruising altitude, N1's RPM continued to rise. Even when I turned off the engine, it still wouldn't stop.
An unsatisfactory experience may be if in the real world it experiences severe damage
As I recall from that incident
I immediately cutoff engines 1 and 4 because it was a very emergency situation. after cutoff the EGT temperature dropped to low after low the EGT temperature rose very drastically to reach more than 3000 degrees Celsius.
And from the peak of the highest temperature, it slowly descends to its lowest temperature.
