Running into Error code 102-243-099 in Pokémon TCG Pocket is annoying, especially when you're just trying to grab your Handy Card Collection Missions rewards and the game boots you back to the title screen. A lot of players have hit this recently, mainly when claiming trainer or tool card missions. What makes it worse is that the mission bar often looks finished even though the game doesn't actually count it as complete yet. The upside is that this is a known issue, and you can usually fix it without deleting or reinstalling anything Pokemon TCG Pocket Items.

What's really happening is a visual bug in the Missions menu. The game sometimes marks Handy Card Collection Missions as "Complete" before you've truly earned the required points from solo battles. When you try to claim the reward, the server checks your actual progress, sees you're short, and throws the error. The fix is straightforward: go play solo battles against AI opponents until you've earned at least 20 points. Once those points are genuinely logged, the mission and reward sync up properly and the error stops appearing.

After hitting 20 points, head back to the Missions tab and try claiming again. In most cases, the reward will go through instantly without kicking you out. Players have been farming this quickly with simple decks and fast solo matches, since you don't need anything fancy—just consistent wins to push the counter over the requirement.

If you're already well past 20 points and still seeing the error, clearing the game's cache is the next thing to try. From the title screen, open the menu in the top corner and choose "Clear Cache." This won't delete your cards or progress, though it may force the game to re-download some data and refresh notifications. Many players report that this step alone fixes lingering sync issues tied to the error.

When that still doesn't work, basic connection troubleshooting can help. Fully close the app, restart your phone, and try switching networks, like moving from Wi-Fi to mobile data or the other way around. Avoid using a VPN, since Pokémon games often flag those connections. These steps can clear up temporary server or network hiccups, especially during busy periods after updates or new content drops Pokemon TCG Pocket Items for sale.

To avoid the problem going forward, it helps to double-check your solo battle points before claiming missions and keep the app updated so you don't miss quiet bug fixes. If the issue keeps coming back, sending a quick report through the in-game support menu can also help flag it on your account. For most players, though, earning the missing solo points and clearing the cache is enough to get everything working again.
