Game has crashe

Hello. I bought the game in January 2019 in Steam, and I have played about 200 hours. During this time, the character managed to reach level 40 and age about 30 years and he had travelled to the island, located in the cell M8, from the free port M7. I used to construct buildings in both places and I had domesticated several animals. When I was trying to hire an NPC, the game crushed many times, but patch fixed it. Then, several times the game had been closed along with the computer screen for reasons unknown to me. Once, just after one of these screen closings, when I was entering the game, it suddenly offered to create a new character, as if it could not find the old one. I created the second character, but I was spawned at once on M8. There were none of my old buildings, and I constucted a new one. After some time, I noticed that strange things were happening, for example, I could raise a wall, which was put long time ago, and after this the chicken disappeared. I decided that this was due to the immediate spawn on the M8 instead of the M7 and tried to create a few more characters. Finally, I managed to be born on the M7, and I was very surprised, because I found there my buildings and animals from the first character, but they did not belong to me:

Then I used admin commands:
Cheat Addexperience 10000 1 1, Cheat TakeAllDino and Cheat TakeAllStructure.
My possessions and creatures became mine again. I took a boat, a horse, and hired two NPCs in order to sail to M8 and see what happened to the property there. After landing, I found there a house built by the second character, and the buildings of the first character there disappeared. I used the Cheat TakeAllStructure again, and noticed that I could lift this long-established building, and I could raise it for a very long time:

I left the game, and when I entered again, I found that my horse had disappeared. For the sake of test, I domesticated a chicken and carried it to my boat.
When I was exiting, I received an error, its text:

When I entered after this error, I could spawn only in this island although no one killed me. And the test chicked disappeared. And all of the items, which was with me, such as weapons, tools, and armor, disappeared too. In addition, the boat disappeared this time: https://yadi.sk/i/S1Sv31EvYKeeCw

I did not notice moment of disappearing of NPCs, but when I saw the boat last time, NPCs had disappeared there already.

I have installed eco's RP Decor mod (but the problem started before the installation, and now the mod is turned off), the Russian localization, which I found among users in Steam, and I changed "-culture=ru" in the language settings of the game, since the text in Russian language consisted of squares, there were no letters.

Save game with the last character:
