Solved crashing when trying to remote self destruct Spectacle Island.

[Mark]

hello again Sim Settlers,
I have reached Spectacle Island on my rebuild tour. long story. broke my game and used a clean save.
In my current save, I am standing to the left of the beached tug where you turn the generator on in the quest.
I am looking towards the ruins of the hotel. I can see the foundations of the city plan I use and some orphaned objects here and there.
my problem is that, when I load the CityManager 2078 holotape and then select the remote self destruct sequence from the tools menu, I exit the pipboy, see the hud message " recalculating build limits " and just when I usually start seeing explosions, the game crashes to my MO2 screen.
should I attempt the remote destruct from a different location?
i have the bridge mod from warwick to the island. maybe I should disable that for the moment in case that is messing things up.
I am going to use my previous save and start from warwick again with out the bridge.
see what happens. in the mean time feel free to give me tips or tell me off

further to the above. I have approached the island (minus the bridge mod) from the south and the south west. both attempts resulted in crashes, as soon as I got near the settlement.
i will try remote destroy from the ruined container raft thing, just off the coast.

and just when I usually start seeing explosions, the game crashes to my MO2 screen.

See if maybe turning the explosion FX off helps.

"Remote Self Destruct Sequence
This will find nearby settlements and offer you the option to tear them down. Once you start, you should stay in the area until it finishes.

If you are having trouble with a settlement crashing and want to destroy it with this, be sure to turn off Demolition FX before you do so, or the extra graphics might crash your game."--https://simsettlements.com/web/wiki/index.php?title=Holotape_Tools#Start_Self_Destruct_Sequence

update as of five minutes ago.
I managed, eventually, to get on the island. I swam slowly from the Castle to the big stack of containers. I even managed to remote destroy the existing SS structures from the beach there.. I had already turned off the explosions. but thanks for the tip bullyrook.
I gingerly approached the workbench and quickly dropped a city managers desk.
selected the plan and chose a leader
cinematic started and it was going great until pop! game crashed again.
no worries I am used to that. now I have a save on the island with a desk ready, I will just keep running it til it takes

well some progress. I got to the point after the cinematic, when the foundations and plots are laid, settlers start moaning about beds and food and water etc the settlement menu hud is loading all looking good and pop! it crashed. i am not afeared though. I will try again.

i am going to leave it as it is for a week in game.
i can't make the plan stick atm.
i discovered that there was a large section of wooden stilt type foundation at the end of the beach.
it hadn't been deleted by the remote destruction. so I ran that again and then it was gone.
it didn't make any difference as the game crashed after the cinematic ended as before.

i'm off to Farharbour. when that is done I will check in on the island.
