Food/Homework (kids, teens and University) disappears when doing the interaction

When my sims are trying to cook a meal, at some point in the task the food disapears, I can´t even click on it, but the sim keeps doing the interaction. When the task is finished, food disappears completely as if nothing is there. 

Homework for kids, teens and University pack also disappears when doing the task, especially on a table. Please help!! this is a very recent bug and I don´t use  any mods or CC.
