sometimes while merging the animals or plants the game pauses and crushes, it stops there while im merging, when i close the game and re-open it again i dont get the plants that i was merging they ...

I merged 5 tier 2 flowers in tropical island and the game crashed. When i restarted the game, they all disappeared.

merged 5 items together, game lagged, i rebooted the game and then they were just gone. i didn't have any merged item nor did i have the original unmerged (it was lvl2 to lv3 of the sugarcane plant)
