As I´ve read by others. When your speed goes high enough the FPS starts to drop and your character goes offscreen, making monsters respawn on your character non-stop.
If you can´t find your saves just read the Instructions shown to the right. It fixes everything. And as Abra said before. The problem is not from his side.. it´s from Kongregate. The save files are saved under the wrong folder. Find them, copy them to the right folder and play on. NO character is missing.. they are just missplaced. Just check every APPData map you have if you have more. I had 3 different ones I had to check before I found the correct one.
For all of you who whines about Call of the Grave. Play the map differently and you won´t get affected by it. Try different things, I just did, and there seems to be a way in every map so you won´t get hit by it.
NinjaKiwi sure understands the "don´t change a winning concept" idea. Still feels like playing Bloons TD 1. Don´t get me wrong. It´s a good TD, but maybe you should change something between the 4 new games.
Totally agree with lots of you... it´s WAY too random.
One fight you crit 2 attacks in a row and win without taking damage.. the next you just stand there and let the enemies whack you 2-3 times without doing anything. Monsters have faster attack speed so you can only hit if they stand still which is silly. Also the Divine Edge is the only way to kill dragons(even with fully upgraded weapon, armor + potion you die) and it´s not 100% sure you will find one. What´s the point in this? It´s a good idea for a game and the graphics are nice without lag/delay, but the game itself is far from perfected.
Found a big glitch. If you have 2 or more of the same towers and upgrade one to let´s say - rank 3.. when you click the upgrade button and quickly press another of the same tower you can instantly upgrade it to rank3 aswell without upgrading it to 1 and 2 first.
