PvP Battle Animation Bug Fix

I'm facing a persistent issue with my game's user interface. During player vs player (PvP) battles, frequently, abilities and their associated animations fail to display. This glitch isn't restricted to certain types of abilities - it affects both offensive and defensive abilities indiscriminately.

This issue tends to occur only during PvP battles, but it happens frequently, disrupting the game's flow and competitiveness. It's crucial to have a full tactical view during these intense battles, and correct visual display of abilities can make or break a PvP interaction.

I need someone with a deep understanding of:

- Game Mechanics: Understanding of the role of abilities in game mechanics is paramount as the issue revolves around this.
- Bug fixing: This is obviously a bug and needs someone accustomed to finding and fixing these sorts of issues.
- PvP environments: As the problem commonly occurs in PvP battles, knowledge and experience in handling issues specific to such environments will be preferred.

Please note the problem is intermittent but frequent. It poses a significant deterrent to the enjoyable experience my game intends to offer its users, hence needs prompt attention and resolution.
