Tooltips?

I am having an interesting problem with tooltips. I am making new spells for a multiplayer map. I get them working in-game, but when I test the map online, tooltips go missing. Interestingly, the tooltips missing are not consistent. Sometimes, all four of a particular hero's tooltips are gone, and the next game, they are all present. Anyway, this is understandably a hindrance to my map, and I was wondering if I could get some help on this. Could it be too many spells? Because, I need something like 120 new ones.

Perhaps someone has an idea? I am doing the triggerwork and terrain for this map, and let me tell you it will be very cool.

Note that when the tooltips go missing, we get the ugly sammy picture for all four spells, but the spells do work. You just have to guess which one is which.

custom loading screens are known to cause problems like this i belive, try using the defaul screen and see if it happens

also make sure you imported everything to the proper directories inside the w3m file
