✅ EFCore issues when removing an entity,
Hello, so currently im having a bit of issues, im using InMemoryDB. So i have this setup where i have an Item(dynamic data) which user can change, and ItemData(static data). ItemData belongs to some ItemCollection(there are multiple item collections). Now when i combine 2 items, i remove them and create next level which i get from ItemCollection.Items, basically next index from current ItemData. Issue araises that when i combine 2 lvl 1 items everything goes smoothly, but second merge, somehow ItemData.Collection only has 2 items, like lvl 1 item got deleted, but then i created myself debug endpoint to check item collection, and it had 1st item too, so something somewhere is wrong, and i cant wrap my head around it, i am always fetching new data when checking item. 
            var item1 = await _context.Items.Where(i => i.Id == request.Item1Id).Include(i => i.Data).ThenInclude(d => d.Collection).FirstOrDefaultAsync();

            var item2 = await _context.Items.Where(i => i.Id == request.Item2Id).Include(i => i.Data).ThenInclude(d => d.Collection).FirstOrDefaultAsync();
            var item1 = await _context.Items.Where(i => i.Id == request.Item1Id).Include(i => i.Data).ThenInclude(d => d.Collection).FirstOrDefaultAsync();

            var item2 = await _context.Items.Where(i => i.Id == request.Item2Id).Include(i => i.Data).ThenInclude(d => d.Collection).FirstOrDefaultAsync();
How i remove them 
                    _context.Items.Remove(item1);
                    _context.Items.Remove(item2);
                    _context.Items.Remove(item1);
                    _context.Items.Remove(item2);
Keep in mind, ItemData has not reference to Item as it does not need to have, but Item has navigation to its ItemData, as it is base information about item.
