3 problems with Ultimate novel & manga scrapper

Hello, i have 3 problems with the plugin (Ultimate novel & manga scrapper) that i purchased : 1) Even with the max execution time set to 3600, the scrapping stops in 25~40 chapters. which i a huge problem for me as i need to run it every time to complete my manga chapters !!! 2) the schedule doesn't work well, i set the schedule to 1 hour but it doesn't work. 3) when i run several rules at the same time the chapters are set to another manga, for example : i have manga X,Y,Z I find manga X chapters in manga Y and manga Y chapters in manga Z.
