Very common problems:
1. perhaps check whether bot is admin --> kickChatMember() would crash otherwise
2. message->chat->title only available in group --> else crash
3. deleteMessage() --> try-catch
4. sendMessage() --> try-catch
5. kickChatMember() --> try-catch
6. bot cannot start a conversation --> all users in "InitiatedChat.dat" can be contacted
8. before automatic functions it needs to be checked whether the message contains text --> join messages do not! --> it would crash
9. use <b></b> (bold) to mark variables in texts --> (..., false, 0, std::make_shared<TgBot::GenericReply>(), "HTML");																									#####CHECKED#####
10. message can only be deleted in a group
11. try-catch around creation of a ReplyKeyboardMarkup
		--> requestContact or requestLocation of buttons only available in private chat (else crash)
