undock instantly after docked

@TestRunner @Insanity i try undock and dock 5 times and it solve!, never undock its self anymore.
maybe i set physic too low because fps drop on my mobile phone

thx for the reply and help!

@TestRunner I think it's physic... When the dock reach 81% and Dock, it will undock instantly.. But when dock reach >91% and Dock, it will stay.. I don't know the physic setting effective or not, because sometime I try 5 times to reach dock more then 85%..
I will test it soon and tell the result...

Thx for the concern

@Insanity thx.. I Will try it

@Dracozard in the settings under quality/physics you can set the update frequenzy. Set it to high, it shouldnt affect performance too much.

@Insanity I trying about 5 docks to make it stay.. Where I can increase the physics?

Ok, after letting it drift around for 10min it finally docked and actually stayed docked, so i dont know why it doesnt work for you, maybe you have lower physics settings? This was done on android btw.
Edit: I even managed to dock a second module that was floating around nearby and both stayed on.

So i've tried a couple of times but i wasnt even able to get it to dock. The magnetic force is too weak and margins of angle and position are way to small for the docking ports. Its just very difficult to get such large crafts to align so perfectly. I'll keep trying but i cant guarantee to succeed.

@TestRunner this is the main station base I made

Take a look

@TestRunner you need the tanker design or the station?

@Dracozard GLHF then!

@MethaManAerospace I have.. And I search other post same with this but never get solution.. :(

have you reported the bug?
