Just create a bot that uses an iterator and a while loop that goes through the loop while the value of the iterator is less than a variable, which in this case equals 1,000. The bot runs fine in Ubot studio when I click run, but when I try to compile the bot, when the task bar gets to 100%, I getting the following error: Offset and length were out of bounds for the array or count is greater than the number of elements from index to the end of the source collection. When I check the debugger, the iterator equals the value of the variable, so the loop is not setting the list (array) beyond
