Linked List Deletion function causing program to crash *wrong pointers?*

Question

In my program when a username is following another one and also has posted a "tweet" which is a string in an attempt to delete the followed username it breaks the program. I believe this is the code snippet in question. If anyone could help me identify the issue I would be thankful as I am learning the usage of linked lists for scale able projects. Thanks

void deleteAccount(accountNodePtr *startPtr, accountNodePtr *curAcPtr, tweetsNodePtr *startTwtPtr){
accountNodePtr acLoopPtr;
accountNodePtr tempCur = *curAcPtr;
followNodePtr followingPtr = tempCur->followingPtr;
followNodePtr tempPtr;
followNodePtr tempPtr2;
tweetsNodePtr iterTwtPtr;
iterTwtPtr = *startTwtPtr;
*below here in question*
    tempCur = *curAcPtr;
while (tempCur->followersPtr!=NULL){
    acLoopPtr = *startPtr;
    while (strcmp(acLoopPtr->username, tempCur->followersPtr->username)!=0){
        acLoopPtr=acLoopPtr->nextPtr;
    }

    if (strcmp(acLoopPtr->followingPtr->username, tempCur->username)==0){
        tempPtr=acLoopPtr->followingPtr->nextPtr;
        free(acLoopPtr->followingPtr);
        acLoopPtr->followingPtr=tempPtr;
    }else{
        tempPtr=acLoopPtr->followingPtr;
        while(strcmp(tempPtr->nextPtr->username, tempCur->username)!=0){
            tempPtr=tempPtr->nextPtr;
        }
        tempPtr2=tempPtr->nextPtr->nextPtr;
        free(tempPtr->nextPtr);
        tempPtr->nextPtr=tempPtr2;
    }

    tempPtr = tempCur->followersPtr->nextPtr;
    free(tempCur->followersPtr);
    tempCur->followersPtr=tempPtr;
}

This is the structure

typedef struct followsNode {
char username[MAX_USERNAME];
struct followsNode *nextPtr;
} followNode;

typedef struct accountsNode {
    char username[MAX_USERNAME];
    struct followsNode *followersPtr;
    struct followsNode *followingPtr;
    struct accountsNode *nextPtr;
} accountNode;

typedef followNode *followNodePtr;
typedef accountNode *accountNodePtr;
