so far i found 2 game breaking bug that can really broke the game :
1. save data corruption during play -> make sure to have backup save
2. teleporting enemy. on certain map where you have kill enemy before it escape or protecting HF core, some enemy can teleport back to starting point/exit. -> this happen when you use alkanese special skill mostly
also i was wondering how can we use magic orb bomb? I bought that on the HF but can't seem to use it. only laser. do i have to progress more or is it bug? i bought 4 of them already and can't be used
